Our Summary and Conclusion
Performance Summary: In every benchmark we ran, regardless of the resolution or the level of anti-aliasing or anisotropic filtering being used, the GeForce 8800 GTX SLI configuration put up the best scores bar none, usually outpacing its competition by wide margins. The GeForce 8800 GTS SLI configuration was also an excellent performer, typically losing out only to the more powerful GTX. In a couple of instances though, the Radeon X1950 XTX CrossFire configuration was slightly faster.
As of today, a GeForce 8800 GTX SLI / nForce 680i SLI combination is clearly the most powerful platform available for hardcore PC gamers. Performance is top-notch, and the feature set offered by the configuration can't be matched by anything else currently. The same basically rings true with the GeForce 8800 GTS, albeit at a somewhat lower performance level. When NVIDIA dubbed the GeForce 8800 GTX and nForce 680i SLI the foundation of the Ultimate Gaming Platform, they weren't kidding. Who needs a wimpy console when a PC can put up triple-digit framerates at a resolution of 2560x1600 with high levels of anti-aliasing and anisotropic filtering enabled?
