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.

SLI does have a bit of overhead versus running a single card, as is apparent at lower resolutions. At higher resolutions, though, the SLI rigs more than make up for it. The SLI system is over 30 frames per second faster than a single GeForce 6800 Ultra at 1600x1200 with 4X antialiasing.
