XFX GeForce 8800 GTS 320MB XXX Edition: The new 320MB GeForce 8800 GTS is an excellent value when you look at its feature set and performance in comparison to the competition. More often than not, the 320MB GTS outperforms ATI's current flagship Radeon X1950 XTX and it hangs right alongside the original 640MB GeForce 8800 GTS in situations where its smaller frame buffer doesn't hinder performance. It is not necessarily a good alternative to the 640MB model for gamers with higher res monitors or XHD capable panels, however. At XHD resolutions with anti-aliasing and anisotropic filtering enabled, the 320MB GeForce 8800 GTS' frame buffer comes up a little short in a few of today's games. And this will likely be the case with many future gaming titles as well. If you've got a XHD capable display (1920X1200 on up), we definitely recommend investing a little extra cash in the 640MB GeForce 8800 GTS or the more powerful GeForce 8800 GTX. If you've got a 19" or 20" panel or a monitor capable of resolutions of 1600x1200 and lower, the new 320MB GeForce 8800 GTS would be a perfect fit. For around $300-$340, these new cards will give you all of the features of NVIDIA's current flagship GPU and plenty of performance, with all of the eye candy turned up in just about any game. Couple that with DX10 support, HDCP compliance, a great video engine, and you can clearly see why the 320MB GeForce 8800 GTS is an extremely enticing product. In addition, XFX's interpretation in particular is a real winner. The XFX GeForce 8800 GTS 320MB XXX Edition card we tested is one of the highest clocked models available, its bundle is well rounded and includes a decent game, it's priced competitively, and the XFX double-lifetime warranty is second to none. The XFX GeForce 8800 GTS 320MB XXX Edition is a clear Editor's Choice winner.
