My post above was primarily a joke...
3dMark 2001 SE is not a CPU benchmark so much as it is a video card benchmark. The TNT2 M64 is so old that I was surprised that it even finished the benchmark. (For reference, my system scores around 11500 on this benchmark.)
MadOnion is the company that distributes this particular benchmark. It's about a 30 MB download. (I do not recommend using the newer 3DMark 2003. I do not feel the results it generates are useful as many very good cards cannot run many of the very heavily weighted tests. Only the Radeon 9500, 9600, 9700, and 9800 cards generate scores that are even worthwhile.)
