Doom 3	Source: id Software

Doom 3 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 the moment, the socket AM2 Athlon64 X2 and FX line of processors really have a lot to offer. There is nothing from Intel's camp that can even keep up. It's refreshing to see the perennial underdog dominate for once.
