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.

At higher resolutions, even a single Asus EN7800GT 2DHTV/256M/OSP/A can play Doom 3 with acceptable frame rates in Ultra quality! It is rather surprising to see how close the Asus videocards perform to the MSI 7800GTX's!
