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 the resolution is turned up the Gigabyte GV-RX80L256V starts to fade relative to the 6800GT and the X800XT card. Doom 3 has always favored nVIDIA cards and here the GeForce 6800GT and the SLI solutions pull out quite a lead.
