Doom 3	Source: id Software

Doom 3 is the most advanced OpenGL game to date. It takes advantage of the latest videocard technology and pushes the processing power of the CPU to its absolute limits. At its highest setting, Ultra quality, texture sizes pass the 500MB mark which means even tomorrow's videocards will have a hard time running everything. The frame rates in the game itself are locked at 60 fps so anything above that point is wasted. Each test is run three times and with the third run being recorded.

As we've seen with other benchmarks and tests, SLI busts out in a big way when the resolution get higher. Our overclocked SLI setup pulled almost 90FPS at 1600x1200 HQ, which is great! It's results like these which have kept SLI viable in the face of the often superior individual performance of ATI cards.
