3DMark2001 SE is a diagnostics tool for measuring the 3D game performance of PCs. It is entertaining and easy to use, which makes it "must have" software for all home PC users interested in 3D games. Even a beginner PC user can get a game performance measurement with 3DMark2001 SE.
Although the 3DMark series is more dedicated to 3D graphics performance, it is rather interesting to see how a faster CPU helps the VGA system achieve higher FPS.
The scores speak for themselves.
