I average about 70 - 80 fps (1024x768 32 bit color) with:
Tbird 1.3 @ 1314 Mhz
GF2 GTS with 12.41 drivers
win2k sp2
384 mb pc 133 cas 2
My monitor refreshes at 85 Hz, so I can't get any high fps then that.
I've written several performance guides in the hardware forum that you can probably find by searching. (I think I named it "optimal performance settings" and there were 2 parts.)
You probably won't be able to get too much more out of a p3 500 though.
