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.

Doom 3 is hard on every videocard but the Albatron Trinity GeForce 6600GT AGP does very well for itself! Those are awesome framerates. Finally the PCI Express versions of the 6600GT show a slight advantage in this most demanding of benchmarks. The advantage of PCI Express is still in the future it seems. Overclocking helps scores here considerably.
