How to Find the Best Digital SLR Lens

If you think that finding a good SLR camera is tough, try to find the best digital SLR lens to go with it.

If you felt there were plenty of cameras to choose from, the number of available lenses is going to be overwhelming.

Digital SLR lenses come in all manner of shapes and sizes, and vary massively in price.
Some are built for the demanding needs of professionals and others are just right for the everyday snapshot photographer.


Faced with all these alternatives, what's a newcomer to the world of SLR photography to do?

Just follow the 6 steps that I outline below and you'll find your way to the best digital SLR lens for your camera.


What Brand Is Your SLR?

Canon EF24-105 F4 L
Before you even get started down the road of selecting a lens, you have to know the brand of digital SLR camera that you're going to get.
Here's why: lenses are not interchangeable.
A lens designed for a Nikon camera is not going to work on your Canon camera - that's what all those Canon lenses are for.
The reason is that modern day lenses have an electronic connection with the digital SLR camera. This connection relays information from lens to camera so that you can change setting on the lens (like aperture) from the camera body itself.
Nikin DX AF-S 35mm F1.8

These connections are proprietary and vary between the camera makers.
The key to understanding which lens will work with your digital SLR can be summed up in two words: lens mount.
Tamron 18-270

The lens mount is the point of connection between a lens and your digital SLR. A Pentax lens mount is different from a Nikon lens mount which is different from a Sony lens mount.
Sigma 10-20mm

This is especially important if you eventually want a lens from a third party manufacturer (more about this later). The key thing to remember right now is that you can get the exact same lens made by a third party company like Sigma, but with different mounts (one for Nikon and one for Canon).

The 6 Steps

I use the 6 steps that I'm about to introduce you to every time I go out looking for a new lens.
Each step is designed to reduce the number of lenses you have to compare by half, which is why it's good to follow the steps in order.
By the time you get to the last step, you should only have to compare 2 or 3 lenses rather than 30.
So here we go - 6 steps to help you find the best digital SLR lens:
  1. Determine the focal length you'll need
  2. Decide if you want a prime or zoom lens
  3. Select a maximum aperture
  4. Choose between first or third party lenses
  5. Evaluate any extra features
  6. Read reviews and narrow your options

When You Wish Upon a Lens

Here's the easiest way to find the best digital SLR lens: write down your decisions as you go through each step of this digital SLR lens guide.
What you are creating is something I call a digital SLR lens wishlist.
A wishlist is really just several questions (one for each step) and the answers that you provide help to identify your ideal lens.

Which Camera : Nikon or Canon

Canon vs. Nikon - which one? It's a common question that comes up when consumers are comparing digital SLR cameras.
These two companies were the first to make the leap from film to digital, and their initial presence in the market make them the dominant players.
Today Canon and Nikon constantly battle for the top spot in the SLR market, while Olympus, Pentax, Sony, Panasonic and Sigma duke it out for a position in third.
If you pay attention to the digital SLR press releases, you'll notice a pattern: when either Canon or Nikon announce a new camera designed to capture some niche aspect of the market, the other company is soon to release a camera to compete.
This page is designed to help you get a handle on the current state of Canon vs. Nikon digital SLR cameras, with a focus on consumer SLRs, not those made for professionals.

Entry-Level Level Cameras

nikon-d60-front.JPG
Let's begin with an introduction to the cameras that get a lot of attention: those geared toward beginning digital SLR photographers.
These cameras are simple: they aren't cluttered with a lot of buttons and features that can be overwhelming for novices.
Instead, they are optimized to produce clear, bright, colorful images whether you use them in full AUTO mode or leverage some of the manual settings.
Canon has two cameras in this this category, while Nikon has three (although the D40x has been discontinued and is hard to find):

Let's take a quick comparative look at the Canon Rebel XS and the Nikon D60, since these are the latest cameras in this category from each manufacturer.

5.0x3.7x2.5in
126x94x64mm
Weight17.7oz (502g)18.4oz (522g)
These cameras have a lot in common, and for me it's a bit of a tie in terms of features and performance.
While you are certainly welcome to try to determine which one has better "image quality" (an imprecise term that is the result of a variety of camera settings), experience using and reviewing photos from a wide range of both Canon and Nikon cameras has demonstrated to me that the photos captured by SLRs from both manufacturers are exceptional.
Since the cameras themselves are so similar I'm going to talk about something completely different: lenses.
One big difference between the Rebel XS and the Nikon D60 is that the Nikon D60 is NOT 100% backwards-compatible with older Nikon lenses — while the Rebel XS works just fine with a large number of Canon and third-party lenses.
If you try to use a lens on the Nikon D60 that does not include AF-I or AF-S (internal focusing motors) autofocus won't work - you'll have to focus manually.
So what does this mean for you - the consumer photographer?
It impacts both the flexibility and price of owning a camera like this for the long term:
  • Flexibility - if at some point in the future you decide you'd like a nice specialty lens (for wildlife or closeups or architecture), your choices with the D60 will be limited (if you'd also like the lens to autofocus)
  • Cost - with the Rebel XS, you can purchase any Canon lens you like, or you can also choose from a wide range of compatible third-party lenses that are often much cheaper - with the Nikon D60, your potential for finding a good deal on a lens is reduced, snce very few third-party manufacturers make lenses that have their own focusing motors
So a lot of your decision about which of these two cameras to get comes down to how you intend to use the camera in the future and how you plan to upgrade.
If you think that you'll replace BOTH camera and lens when you upgrade, then either the Rebel XS or the Nikon D60 will work fine. If you'd like to build up a collection of lenses (without spending a forture) that you can continue to use on future cameras, then the Rebel XS is the better choice.

Intermediate Cameras

The next stage of the Canon vs. Nikon battle are the cameras geared toward photographers who have some experience taking photos with SLR cameras (either film or digital).
The cameras in this category often bridge the gap between the entry-level cameras and those designed with more professional photographers in mind.
Currently, there are two Canons and two Nikons in this category:

These two cameras really are on a pretty even footing.
Some of the big differences include:
FeatureDifferenceAnalysis
Video Mode
  • T1i (500D): 1080p
  • D5000: 720p
While the T1i can capture higher resolution video be aware that this will create humongous file sizes. Sure, you can play back videos at home, but uploading them to share online will take HOURS.
LCD Screen
  • T1i (500D): No flip, High Resolution
  • D5000: Flip, Lower Resolution
The LCD on the D5000 flips out from the camera body and rotates - great for high and low angle shots. However, if you don't take a lot of photos from bizarre angles, then the higher resolution screen on the T1i will display images that are clearer and a better color match to what you will eventually see on your computer monitor.
ISO Range
  • T1i (500D): 100 - 12800
  • D5000: 100 - 6400
Sure, you can boost the ISO on the T1i into the stratosphere, but the amount of digital noise at settings higher than 6400 will definitely affect image quality. Very high ISO settings are most useful when you take photos of moving subjects in near dark.

Pro-Sumer Cameras

canon_40d_side
In the pool of digital SLR camera buyers, there's a cluster of advanced amateurs — they are also called "Professional Consumers" or Pro-Sumers for short.
Pro-Sumers are looking for a bit more functionality from their cameras than what's offered by the true consumer models, and they're willing to pay more for increased image control.
What sets the pro-sumer cameras apart from the others is their sheer speed.
Most digital SLR cameras are capable of capturing about three consecutive photos per second - and this is just fine for anyone passionate about landscapes and portraits.
But action junkies need a bit more from their digital SLR - the ability to rapidly capture several consecutive frames for that one action shot that is a real winner.
The minimum consecutive capture speed of cameras in this class is 5 photos per second (the maximum - if you're curious - is 8 per second).
Paired with this impressive speed are advanced autofocus systems, and about a hundred different ways to customize the camera to suit your specific shooting style.

Once you get up to this level of camera, the question of which one to get - Canon vs. Nikon - is less about comparing features and more about name recognition.
I've talked to enough people interested in digital SLR cameras to realize that they often have a built-in bias about one company.
Some people lean toward Canon because it is such a prominent name in the industry (and because they also have a wide range of very popular compact cameras) while those that have used Nikon gear in the past are firm that they will never switch brands.
Both companies are well aware of this brand loyalty, so the cameras that are available in this category satisfy the needs of the most demanding photographers.
If you're fanatic about Canon cameras, then the 50D has all the features that you could ever need to capture stunning images. Those who lean toward Nikon should be blissfully happy with the D300 in hand.
I will state one personal difference that I have found working with these cameras: if you are interested (now or in the future) of taking a lot of photos using flash instead of natural light, then go with Nikon.
Nikon has done a great deal of work to ensure that their cameras communicate well with their flashes - something Nikon calls the "Creative Lighting System" or CLS for short.
With relatively little fussing, you can quickly set up three independent wireless light sources, and you're able to control the amount of light output from each flash directly from the camera.
While you can certainly achieve the same effects with a Canon digital SLR it takes more gear, costs more and doesn't have quite the same plug-and-play simplicity of the Nikon system.

Apple Mac or Intel-Window

To compare Mac and PC is not that difficult.
So, if you had to pick one, which would you choose? A Mac or a PC?
Below is a brief Mac vs. PC review and overview. I will list as many pros as possible about each one.


Why Macs are Better

imac
- Macs give you the ability to run OS X and Windows both (legally).
- Macs work great with other Apple components such as the iPhone, iPod Classic, iPod Nano, iPod Touch, iPod Shuffle, etc...
- Macs are very simple to use.
- Macs are less prown to computer viruses, although they can get viruses.
- Purchasing a Mac gives you Apple Store support.
- Apple uses quality parts to manufacture Macs.
- Macs are trendsetting, designed well, and visually appealing.
- Macs come with better software, out of the box (iLife).
- Macs give you out of the box access to the iTunes Store, if you are an iPod or iPhone user.
- Out of the box, Macs are not loaded with trials and additional software.
- Apple has top of the line phone support.

Why PCs are Better

pc- You can build a PC from the ground up, picking each individual component. PCs give you maximum customizability.
- PCs are generally cheaper in price. You can get the same processor, amount of RAM, and hard drive capacity for much cheaper with a PC.
- Branded PCs are a wide market. You have many options when it comes to choosing a PC: Dell, HP, Gateway, etc... There are really only 6 types of Mac computer: MacBook, MacBook Pro, MacBook Air, Mac Mini, iMac, and Mac Pro.
- PCs have better software compatibility. You can find practically any software for PC. Macs are more limited in selection.
- PCs generally have better backwards compatibility. You can run Windows 7 on a 5 year old PC. You cannot run Snow Leopard on a Power Mac G5.
- More people use PCs. Thus, PCs have a larger support community behind them.
- The majority of businesses use PCs.
- PCs are better for gaming.
- PCs have more compatible accessories than Macs.
- PCs are more upgradable.
- PCs are open source.

Conclusion

To compare Mac and PC... Which one is better? It's all personal preference. I'm sure that's not what you wanted to hear, but that's the best answer. In the above review, you can see that both of them have some great advantages. Some people like Macs better, some people like PCs better. Thus, some people absolutely hate Macs, and some people absolutely hate PCs.
It's all an opinion, a preference.


iPhone 4 vs. Android

Apple unveiled its latest magical and revolutionary product this week: the new iPhone 4, also known as "the phone that guy from Gizmodo showed us seven weeks ago."
From a hardware perspective, the new iPhone is a significant improvement over Apple's last offering. And on the software side, the updated operating system brings about numerous capabilities previously unavailable to iPhone users.
The problem, though, is that most of the iPhone's new features feel like incremental upgrades, not game-changing innovations. Put simply, the new iPhone is a step forward within Apple's world -- but outside of that walled garden, it's still worlds behind.


Apple's iPhone 4 vs. Android: The Basics
Let's go through the biggest selling points of Apple's new iPhone 4, as outlined by Steve Jobs in his keynote on Monday:

• It's pretty. The new iPhone has an updated design, with a thin 9.3-millimeter profile and a stainless steel shell.

• It's sharp. The iPhone 4 boasts a new 326-DPI, 960-by-640 LCD display.

• It's faster than the 3GS, thanks to the addition of Apple's custom A4 chip.

• It has a better camera, plus a new front-facing camera that allows for (limited) video chat.

• It has new features from the iPhone OS -- err, sorry, iOS -- 4.0 release. These include primarily things that have been available in Android-powered devices for some time, so we won't spend much energy focusing on them here.

• Oh, and it also has that gyroscope thingie.
iPhone 4 vs. AndroidPitted up against the HTC EVO 4G, arguably the highest-end Android phone on the market right now, the iPhone 4 comes out ahead in the display department: Its 960-by-640 resolution beats the EVO's 800-by-480 resolution, though the EVO offers a larger screen (4.3 inches next to the iPhone's 3.5 inches). The new iPhone is also about a tenth of an inch thinner than the EVO.
Do those advantages have you seeing stars? Because they're pretty much where the new iPhone's competitive perks end.
(I know, I know: I left out the gyroscope thingie. Quite frankly, I'm not sure most typical users will understand or care what it is, let alone notice the difference it makes. If it excites you, feel free to add it into the list above.)

Apple's iPhone 4 vs. Android: The Smackdown 


Apple vs. AndroidConsider now where Android, despite this week's iPhone progress, comes out ahead. We'll start with the basics on the handset-to-handset comparison:



• The EVO has limitless video chatting, whereas the iPhone's "futuristic" video chatting works only over Wi-Fi and only with other iPhone 4 users.

• In speed, the EVO uses a 1GHz processor. The iPhone, meanwhile, is said to use the same A4 processor as the iPad, which suggests it also has a 1GHz chip (Apple hasn't explicitly disclosed the processor's specifics). No formal device-to-device benchmarks have been completed yet, but some initial impressions suggest the new iPhone may not be noticeably faster than its predecessor. Either way, new cutting-edge Android devices will be coming out practically every month; this iPhone will likely be the only hardware available until Apple's next hurrah in 2011. You do the math.
Then there's the other important stuff the new iPhone is still lacking:
• The existence of full multitasking, outside of carefully defined and limited circumstances.

• Any significant customization options (and no, the ability to set your own wallpaper doesn't count as significant, even if Steve Jobs says it's "amazing" and "really wonderful"). Don't like Android's interface? No problem: You can change almost every facet of the user experience, should the urge strike.

• System-wide voice-to-text input.

• Live, functioning home screen widgets.

• The ability to swap out the phone's battery.

• High-quality navigation software that isn't a separate purchase.

• Anything that matches the numerous innovations coming from Android 2.2 -- things like over-the-air music syncing and streaming, cloud-to-device messaging, and mobile hotspot functionality.

• The choice to use a carrier that isn't AT&T (I don't think I have to spell out the numerous reasons why).

• Tethering that doesn't cost you $20 a month.

• The ability to install any app you want, even if it's something morally objectionable -- you know, like porn. Or political satire.

• The ability to use an app that Apple sees as competition, like Google Voice.

• The ability to view Flash-based content on your phone. (See also: Why the Apple crowd's completely wrong about Flash)

• The ability to use your device the way you want -- not the way Steve Jobs thinks you should. 
(Side note: I read somewhere that the new iPhone has a handful of hidden features most people don't know about. If anyone ever sees the "Soul Scanner" in action, let me know and we'll re-evaluate.)

Apple's iPhone 4 vs. Android: Final Thoughts
In the end, there's little question that Apple's new iPhone will be a commercial success. And hey, if you're the kind of person who buys into Apple's world, you'll probably love it (in fact, I think that might be a contractual requirement).
The tides are turning, though, and more and more people are starting to realize that there is a more powerful and open alternative. Yes, the old "but what about the apps?" argument is still out there -- but it's becoming less relevant with each passing month. And, let's be honest, does anyone really need more than 50,000 apps to find what they want? The vast majority of Apple's selection sits unused.
Here's the truth: Steve Jobs is many things, but stupid is not one of them. He's undoubtedly aware of the strides his competition is making in mobile technology, and he's undoubtedly made a conscious decision to do things his way, with his control, instead of trying to keep up with the paces. It's a decision that should feel awfully familiar to Steve and the Apple empire; they've been in this boat before, and we all know how it ended.

So mark my words: This won't be remembered as the year the iPhone got folders, a faster chip, or a gyroscope. This will be remembered as the year the iPhone stopped paving the way and started transitioning into the third-place platform -- albeit, the very pretty third-place platform -- it's destined to become.
Not that there's anything wrong with that.

Graphic Card : ATI or Nvidia


If you're a gamer, it's all about graphics quality. The best graphics card produces the best image quality - vital if you're immersing yourself in a shoot 'em up or an MMORPG scenario. Even if your applications are a little more serious such as CAD auto programming or graphics packages, your work will only be as good as the tools you use. The proliferation of high quality graphics cards have given the discerning PC user plenty of scope for upgrading and the two most popular suppliers have been ATI and Nvidia. But which is better?


Cutting edge graphic tech
ATI 5870
Nvidia rocked the graphics world last year with its introduction of a dual 3D-card SLI set up. But an SLI setup requires a motherboard upgrade, high voltage power supply and two identical SLI graphics cards. All pretty high tech stuff, and not for the uninitiated. Thankfully, both Nvidia and ATI supply a range of graphics cards to suit all pockets, all levels of technical competence and all types of requirements. Take that latest buzzword, 3D. You don't have to go down the dual SLI route to achieve a 3D effect.
Nvidia GTX480
Nvidia has products that will have you ducking incoming fire or zooming through the blue-tinged world of Avatar in glorious 3D. ATI, although not 3D ready just yet, are working hard to get their cards 3D-capable and bring them to market. However, 3D ready cards are going to require a hefty investment of several hundred pounds. If you're a committed gamer then that may seem like small change, but for sporadic gamers or those who merely want better graphics without the 3D bells and whistles, it might seem a bit steep when compared to other graphics cards on the market.
For those who have invested in the latest Windows 7 package with DirectX 11, both ATI and Nvidia have graphics cards to complement. The ATI 5000 series and Nvidia's 400 series are all DirectX 11 compatible and provide gamers with exceptional quality graphics, quick frame speeds and multi-screen gaming capabilities on the very latest cards.

Mid range cards


Nvidia GTX460

For those on a limited budget but who still want to upgrade their graphics capability, then both suppliers have a plethora of graphics cards that do the business. Both ATI and Nvidia have cards that are reasonably priced, give you fast frame speed, 3D graphics and excellent image quality.

ATI 5770














Bargain basement
The two arch rivals have one thing in common - they both know that their market isn't just made up of cash-flush hardcore gamers willing to spend top money on their graphics cards. The trouble is with the low range cards though, is that many of them will not have the frame speed or image quality to play the most recent games on, and the whole experience will be lacking that special something - namely not having to wait every few seconds for the frames to load.
Nvidia GT220

ATI 5570

However, if your PC uses an integrated graphics chip and as long as you're not trying to run too many applications at once, a low price graphics card should be able to cope with a reasonable amount of processor demand without completely pixelating your images. It may be tempting to opt for a graphics card that has its own 128MB of memory and doesn't piggyback off your main processor, but by using a card that does borrow from the system memory cache you can effectively get a cheap alternative to dual processing.
Both ATI and Nvidia have their plus points, particularly in the more high end packages. But, as we asked at the beginning, which is better? Well, the honest answer is neither - they're both as good as each other depending on your requirements, your OS and how deep your pockets are.

The standard rule for graphics cards applies - the more you pay, the better the results. And with more gaming manufacturers embracing 3D, it might be time to think about putting a little more financial investment into your graphics package.

Choosing your new Processor

There are countless companies in the computer industry but there is only one battle that counts... AMD vs. Intel. This is a favorite topic in the forums, yet instead of blindly pledging allegiance to one CPU or the other, let's take a look behind the scenes and find out which companies processor is the best bet.
Now I should say that I'm a hardware enthusiast at heart, so for me CPU performance matters the most. I stick with gear only as long as it keeps my PC at the front of the performance curve. After that, I drop it like a rock and move onto greener pastures, regardless if it's the same brand or not. After all, what's the point of brand loyalty? AMD and Intel don't love you back, no matter how much you might sing their praises. Put another way, it's not like AMD only sells to you, or Intel has a smiling shot of your mug on every pay stub as a testament to your past processor purchases now is it?
The nice thing about being computer enthusiast is that right now both AMD and Intel platforms support a lot of cross compatible hardware. Sure the CPU and motherboards are platform specific, but you can share DDR2 memory, videocards and other peripherals easily enough. If PC speed is what you crave, you can jump from one processor platform to the next ever couple months, taking your memory, videocards, hard drives and everything else along with you.
Anyway, the point I'm trying make is this. As a hardware enthusiast you have the pick of some of the fastest computer hardware on the planet. Ignore the urge to stick with AMD or Intel out of tradition, go out there and find the best gear based on benchmarks!
So, who offers the best performance - is it AMD or Intel? I'm glad you asked, the answer is....
...Intel. For the moment anyway, Intel's dual and quad core processors are the king of the heap. In particular, the companies Core 2 Duo/Quad processor lineup is out-pacing AMDs current Athlon64 X2/FX processor families. That may indeed change by the end of Q4'07, or it may not.


AMD is partly to blame for its current situation. Big green has not refreshed its CPU lineup since the last time PCSTATS dished the dirt on the AMD vs. Intel slugfest. AMD won the battle back then, but relying on the now somewhat dated K8 Athlon64 processor has left AMD without a good competing CPU for Intel's "Conroe". Intel published performance results on "Conroe" for quite some time before it was officially released, so it's not like AMD was blindsided by it either.
Intel Climbs Back To The Top
For its efforts, Intel has undergone more than a few self-evaluations. It had to deal with a "Prescott" Pentium 4 voltage leak issue, it stopped pushing GHz as the singular processor metric and adopted the same kind of rating system AMD had been using for years. Then, Intel abandoned Netburst and modernized the P6 core into what we now know as the Core Solo and Core 2 Duo processor.
The Core Solo was nice, but Intel's Core 2 Duo is the real beauty. The CPU was an immediate hit among gamers from the time of its release, and it continues to out pace comparable Athlon64 processors.
Intel's previous NetBurst architecture had de-emphasized FPU power in favor of special instructions (SSE, 2, 3). This is partly the reason so many gamers ditched their Pentium 4/D computers in favor of AMD Athlon64 processors and it's more powerful FPU.
With the Intel Core processor architecture, the company finally addressed the FPU issue. Intel's "Conroe" CPU core has a very powerful FPU, and that has guaranteed a very welcome reception by gamers ever since.
As it stands in the fall of 2007, the Intel Core 2 Duo processor is generally more powerful than AMD's Athlon64 X2/FX series in games, and all around.
Whether you're working on multimedia tasks, workstation or just need raw data crunching power, the Core 2 Duo trounces AMD's best almost every time.
It's also proved its mettle as an excellent overclocker!
Early stepping Intel Core 2 Duo processors could overclock to 3.2 GHz+ on air cooling, and the recent 'G0' stepping can go even further. I've overclocked to the region of 3.8 GHz with the stock heatsink in fact.
By comparison, AMD's 90nm Athlon64 X2/FX processors have difficulty overclocking much past 3 GHz.... Make no mistake about it, clock for clock Intel's Core 2 Duo is currently faster than AMD's Athlon64 X2 and FX processors.
Thermal Output Improving
The Intel Pentium 4 and D processor series were notorious for consuming a lot of power, and consequently running quite hot. The architecture Intel based the Core 2 Duo processors on is much better in this regard. While Pentium 4 architecture was at one time headed towards 150W TDP (Typical Design power), many of its current processors are now pushing 85W or less. One generation before, Intel Pentium D CPUs hovered around the 125W TDP range, late model Core 2 Duo processors (like the E6750 ) have a 65W TDP!
It's true enough that the power values AMD and Intel specify are not entirely comparable with each other, but total system power measurements give a good basis for comparison. I've conducted some power draw measurements recently, and those tests showed that Intel is genuinely kicking high power habit. An average Intel Core 2 Duo E6750 based computer system draws about 7W more power than a budget AMD Sempron 3600+ based PC system with its single CPU core running at idle. You'd think the lower power budget AMD chip would be significantly easier on the juice than the fairly high end E6750 Core 2 Duo, but the difference is pretty small.
With an Intel Core 2 Duo system under load, total power draw results are impressive. For instance, a Core 2 Duo E6750 system consumes 163W of power (total PC power draw) when running with both CPU cores under load.
A comparable Intel Pentium D 940 system consumes 253W of power with both processing CPU cores stressed, and an AMD Athlon64 FX-62 power system consumes upwards of 235W! It's clear you can save a lot on the utility bills by switching to a CPU that sips electricity. Intel offers this, with great performance. (Please keep in mind that these are total system power draw values, not just the processor.)
I've often thought that Intel is the more innovative of the two companies when it comes to designing heatsinks for its processors. The current Core 2 Duo bifurcated radial fin heatsinks are remarkably good, and very quiet.
Gone are the days of throwing out the stock heatsink for an after market cooler the second the box is opened... For good all around CPU cooling, it's tough to beat Intel in terms of noise level. The stock heatsinks are just so quiet, thanks in large part to 90mm fans and Pulse Width Modulation which allows the rotational speed to vary based on moment to moment thermal output.
Of course, these aren't the only reasons Intel is leading with the Core 2 Duo, as we'll talk about next, chipsets play a big role....

Chipsets and Dual Videocard Support The one thing that has propped up AMD for the longest time was wide support for dual videocard gaming - both nVIDIA SLI and AMD CrossFire technology. For Intel users who wanted to run dual videocards, there was no real option for the longest time.
That was eventually sorted out when Intel added support for dual videocards (ATI CrossFire) to its P965 Express chipset. A few Intel Edition nVIDIA nForce 590SLI motherboards also brought SLI to the Intel platform, but they weren't released in very significant volumes. That Intel Edition nVidia chipset seemed to be EOL'ed rather quickly too.
The situation is much better for gamers looking to run dual videocards with a Core 2 Duo processor nowadays. nVidia's nForce 680i/650i series motherboards are readily available, and Intel's P35 Express supports AMD CrossFire technology better than the P965 Express.
The upcoming Intel X38 Express chipset is rumored to support both nVIDIA SLI and AMD CrossFire! AMD has certainly lost its well deserved monopoly on multi-videocard gaming platforms. Which CPU will take the lead in quad videocard gaming platforms remains to be seen...
It's Always About The Price
Intel has been unusually aggressive with the pricing of its Core 2 Duo/Quad processors this year. Consumers have benefitted surely, but what cost us nearly $800 last CPU generation entered the market at just $300!? I don't know how they do it.
Still, I have to tip my hat towards Intel, not only are its emerging CPUs fast, they're just such a bargain. As of this writing, $120 US will get you an Intel Core 2 Duo E4300 processor which is perfectly adequate for a workstation or home PC. A year ago, an equivalent class of processor would have been 2-3 times as much.
If you're building a new computer or buying a mainstream PC, a very nice Intel processor will only set you back $150-200US. For that, what you'll get will be faster than the AMD equivalent at that price. Factor in the cost of the other computer components, the fact that going AMD is no longer 'the cheaper option', and it really just makes sense to build Intel this time around.
When it comes to budget computing, the lines become blurry. Intel's budget Celeron D processor is still based on the Pentium 4 architecture, so there are those downsides when held up to the light of the current Core 2 Duo architecture.
It's a tough call. I suppose if I were putting together a budget PC right now I might just opt for a Celeron D instead of an AMD Sempron, mainly because of the flexibility of upgrading that LGA775 socket to a Core 2 Duo CPU at a later date. Now the socket AM2 AMD Semperon is a better budget processor all around than the Celeron D, but the upgrade path for AM2 just isn't as alluring right now. Like I said it's a tough one. The choice seems to be sacrifice a little performance now for better upgradability down the road, or benefit from entry level performance now and sacrifice upgrade performance later on.
The Ebb and Flow of CPU Architecture
Blind loyalty towards one brand precludes you from the decision making process. Is 'A' better than 'B,' or does 'B' have a better marketing program than 'A'? If you're not up on current CPU tech, this kind of decision making can quickly turn confusing.
Consider this; AMD and Intel are both corporations in the business of making microprocessors. The aim of a corporation is to make money, there's no hidden agenda to that. Intel has proven that in a short span of time, it can re-engineer a failing processor lineup and completely turn around its fortunes. AMD has shown us that in that same period of time a stagnant processor architecture can loose momentum because of a lack of innovation on a timely basis.
This is the ebb and flow of the tech industry, despite their commitment to convince you otherwise...

One CPU Core Against the Other Having no preference to Intel, no preference to AMD, allows you to understand that as a consumer, hyper-competitive companies tend to trade market dominance from one season to the next. 'A' is not always going to be better than 'B', and vice versa.
It'd be nice to have a third option, a 'C' to choose from, but sadly all of Transmeta's best technological advances have come under the Intellectual Properly gavel. Still, the impact it had on energy efficient processing is due more credit than history has bestowed... but that's a story for another day.
As it stands right now, Intel dominates the processor market - in value, in performance, in inertia. I'd be remiss to count AMD out just yet though.
AMD has been delayed by technological kinks, missed release dates that may have kept it in lock step with its largest competitor, and for better or worse swallowed $5 Billion in debt for ATI at the beginning of this year. There are positive signs from AMD if you know where to look though...
The AMD 690G chipset is a resounding success for example, and if Intel has taught us anything, it's that chipsets pave the path to PC dominance.
AMD has not been asleep at the wheel on the processor front either. Much delayed perhaps, but not asleep. It is readying a new core, called 'K10', and a slew of intermediary processors based on 'Barcelona.' Not much is known about the performance of AMD's upcoming 'K10' Phenom X2 and Phenom X4 desktop processors right now, but we should find out very shortly if the 'Agena' and 'Kuma' chips will give Intel a run for its money.
While much of AMD's success the last few years can be traced to its partners, Intel has guaranteed the success of the Core 2 Duo processor with well designed chipsets. As they say, "it's the chipsets, stupid."
The Intel Core 2 Duo is a very efficient processor, its TDP values are roughly half of what the Pentium 4/D series use to be, and real world testing shows that complete computer systems equipped with an Intel Core 2 Duo use considerably less power.
This is all well and good, but the real ace up Intel's sleeve is not that it has a processor which is faster by some percentage points, it's that the Core 2 Duo is faster and aggressively priced! I can't remember a time when you got so much value in a CPU for so little.
Mind you, Intel's Extreme Edition processors are still priced in the stratosphere, but its regular desktop CPU lines are very affordable. Compared to AMD processors in the same price bracket, Intel has the upper hand.
So as these things go, when it comes to AMD or Intel? Intel wins this round. The bottom line is simply that Intel has outmaneuvered AMD, scrapping an entire generational branch of CPUs for a double headed offshoot that rocks. The Core 2 Duo performs really well, so it's what I've been recommending.
But before we close up this debate, there's one more point you should consider. Along with casting away brand loyalty and judging CPUs based on cold hard benchmarks, there's another option we rarely see mentioned on sites set with deconstructing the latest and greatest technology. If the computer you have right now does what you need it to, you really don't have to choose between AMD or Intel's latest do you? ;-) 
  


Which One ,Xbox 360 Slim or PS3 Slim ?



First came the Xbox 360 then came the Sony PS3, then the PlayStation 3 Slim followed a few years later. Now in 2010 Microsoft has put its games console on a diet and we will soon have the Xbox 360 Slim – but can we really call them slim, as they are not as thin as we all assumed they would be.


We do now want to take it away from Sony or Microsoft; they have done a good job packing all that technology in a smaller case. We know that Sony improved its graphics chip to one that offers increased performance while keeping power consumption and heat to a minimum.
When I saw the Sony PS3 Slim for the first time I did not know what to think of it – I had a hard time coming round to its design. I am afraid that I still get that vibe; I love the fact that it is smaller but I hate the finish. I still like the glossy black and stainless steel finish of the original PS3.

However, I think the total opposite of the Xbox 360 Slim – the original console is just a big lump of plastic packed with some great hardware. The new slim version looks much slicker and will be shouting to you on the store shelf – buy me.

I will admit that I prefer the Sony PS3 for my gaming needs, but I find myself falling in love with the sexy design of the Xbox slim.

So which one?

Firstly you need HDTV (res 1920x1080) for both console and XboX game is much easier and cheaper to buy, but PS3 games so much fun to play but the game cost higher ....

Honestly I rather pick PS3 cost Sony is well known for its gaming console and can be connected to my beloved PSPs
