well the thing is the entire GF4 line up in general were kinda lackluster. The R300, 9500/9700 Pros were just utterly dominate. The scores below are from what I've tested so far on my 3.6Ghz P4 northwood. Even the FX line up struggled to compete with the ATI cards back then. It took the 6800 series to finally get nvidia back the crown.

Keep in mind as well that R300 came out later. Only a few months later, but NV25 did hit the scene first and was considered the benchmark to beat, so R300 had to be faster. The GeForce FX series was a disaster from the start due to nVidia trying to cash in on the 3Dfx acquisition by pushing that design team to create a "feature rich" architecture on a new node that could stretch enough to beat R300. They completely fucked themselves with their SM2.0 implementation and giving ATi time to refine R350 and R360 by waiting for 130nm.
