The GeForce 8800 GTS is the little brother of the 8800 GTX, and both are based on the same Nvidia next-generation DirectX 10 GPU. The 8800 GTS is slightly crippled compared to the GTX, but it will still beat powerhouse cards like the dual-GPU 7950 GX2 in many cases. The card isn't notably slower than it's 640MB 8800 GTS cousin, which costs quite a bit more

Best PCI-E Card For ~£250 / €350: Tie

The Radeon HD 2900 XT debuted with mediocre performance compared to the GeForce 8800 GTS 640, especially when price was factored in. But ATI has stepped up to bat and introduced fresh drivers that really bring out the 2900's potential, even allowing it to challenge the 8800 GTX in some arenas.

Even so, the 8800 GTS 640MB is still a great card and can challenge the 2900 XT in some titles, and on average you will find the 8800 GTS for less money. With this in mind, both cards are recommended in this price segment.

The GeForce 8800 GTS is the little brother of the 8800 GTX, and both are based on the same Nvidia next-generation DirectX 10 GPU. The 8800 GTS is slightly crippled compared to the GTX, but it will still beat powerhouse cards like the dual-GPU 7950 GX2 in many cases. The biggest downside to the 8800 GTS 640 MB is that its cheaper 320-MB cousin offers very close performance for much less scratch. However, if you plan to play your games at high resolutions 1600x1200 or above, it's worth the extra money for the 640MB version.
