Well, to do this comparision, basically just compare a Radeon 64 vs. A GF2 GTS, which there are plenty of comparisions like that around. But the bottom line, is that a GF2 will have better frame rates at lower resoultions, but the higher you go, the higher performing the Radeon will be because of HyperZ. Oh and in terms of features, well A Radeon has better DVD playback I believe, but that's all I can think of.
