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, with the third run being recorded.

Doom 3 is hard on pretty much every videocard on the market right now, so it's no surprise to see that HQ mode and 1600x1200 is too much for this mainstream card. High quality and 1024x768 is very good though, and gives gamers decent framerates. Overclocking helps too.
