<<<<TOP 10>>>>
1) ATI Radeon X1900 :hap2:
ATI's X1900 cards, which so far come in XT, XTX, and Crossfire versions as well, are at the top of ATI's current product line for gamers. The performance is very similar to that of GeForce 7 cards. As with earlier ATI cards, the X1900 XT is better than the plain X1900, and the XTX is better still. The X1900 features an impressive 48 shader units and some versions have 512 MB of memory, but they don't come cheap.
2) nVidia GeForce 7900 GTX
The GeForce 7900 is nVidia's premium chipset for gamers, and has several improvements over the 7800. As well as better performance, it's smaller, has fewer transistors, and generates less heat. Subsequently, it should cost less to manufacture cards using the 7900 than the 7800 in the long run, but at the moment they are quite expensive. To be sure, it's a force to be reckoned with and keeps up to the Radeon X1900 XTX on most benchmarks.
3) nVidia GeForce 7800 GTX
With 24 pixel pipelines, 8 vertex units, and an astonishing 302 million transistors, the GeForce 7800 is one of the most complex graphics processors ever built. By comparison, an Xbox GPU has 60 million transistors. Like GeForce 6 cards, the 7800 supports SLI (Scalable Link Interface), which is nVidia's dual card solution.
4) ATI Radeon X1800 XT
The X1000 series from ATI so far includes the X1900, X1800, X1600, and X1300. The X1800 XT is one of their premium offerings with ultra-threaded 3D architecture, improved memory controller efficiency, and Shader Model 3 support. It outperforms the GeForce 7800 GTX on many benchmarks despite having fewer pipelines, and the core hums along at 625 MHz.
5) nVidia GeForce 6800 GT
nVidia's GeForce 6800 series represented the largest leap in game card performance to come along in years. They support DirectX 9.0c and Shader Model 3.0 and are available for both AGP and PCI Express. Note that the 6800 Ultra wants two auxiliary power connectors, so you might want to go with the 6800 GT, which only needs one. An excellent card that should get more affordable now that the 7800s are out.
6) ATI Radeon X850 XT
A slightly older chipset from ATI targetted at gamers is the X850, which is available in Pro, XT, and XT Platinum Edition (PE) versions. There is also a Crossfire Edition for those of you interested in running a system with two graphics cards, though this is prohibitively expensive for most purposes. The X850 can be found for AGP and it's a nice choice for a relatively affordable upgrade if Shader Model 3.0 support isn't important to you.
7) nVidia GeForce 6600 GT
Although very similar to the 6800 cards, including DirectX 9.0c and Shader Model 3.0 support, nVidia has made some changes to make the 6600 series more affordable. They have fewer pixel pipelines, fewer pixel shader units, and the memory bus has been reduced to 128-bit from 256-bit, but they still offer exceptional game performance. AGP versions of this card are also available, and recent price drops have made the 6600 GT a great value.
8) ATI Radeon X1600 XT
The Radeon X1600 is a mid-range chipset from ATI aimed at those seeking something easier on the wallet than the X1800 and X1900, but better performing than the X1300. It is very comparable in both speed and price to GeForce 6600 technology. Although the X800 is a little faster in some cases, you may want to go with an X1600 because it has Shader Model 3.0 support, which X800 and X850s do not have.
9) ATI Radeon X700
The X700, X700 Pro, and X700 XT are some of ATI's older mid-range cards, originally meant to compete with nVidia's 6600 line. They fall roughly between the vanilla GeForce 6600 and the 6600 GT on many benchmarks. You can now get PCI Express or AGP models of this card. A decent value even before the X1000 cards put downward pressure on the price, but no Shader Model 3.0 support, which more games are now using.
10) ATI Radeon X1300 Pro
Radeon X1300s are designed for gamers on a budget. They don't really compare in performance to other cards on this list, but they do support Shader Model 3.0 and they run most games adequately at lower settings. I recommend the Pro model because it's a little faster than the vanilla X1300. With some shopping around and maybe a rebate, you should be able to find an X1300 Pro card for about $100
