Doom 3 - Delta Labs
We'll kick off our gaming benchmarks with Doom 3. Our first Doom 3 test uses a gameplay demo we recorded inside the Delta Labs complex, and it represents the sorts of graphics loads you'll find in most of the game's single-player levels. We've tested with Doom 3's High Quality mode, which turns on 8X anisotropic filtering by default.

Without antialiasing, the GeForce 6600 GTs in SLI are beaten only by the other SLI configs; not even a single GeForce 6800 Ultra can keep up. However, once antialiasing is turned on, the 6600 GTs in SLI drop back a little. At 1600x1200, the 6600 GTs in SLI are still putting up quite a fight, though, only three frames per second behind a single GeForce 6800 GT.
