I am trying to figure out which driver would offer the best preformance under XP Pro - the one that Xp provides or the 3rd party one I fould at the 3dfx site (c3-4-5_wxp_ice2.zip. Thanks in advance for the help.

the one that XP provides, well to put it bluntly SUX, the third party one you have chosen is a good 1, but there are several others too, just remember to run the course and click right thru the errors, then run setup again and this time choose repair and it should install them fully. To bad nvidia threatens anyone that tries to write drivers for them.

There is a set of win2k drivers out there that were fixed to install on XP. I can't remember the website. They should'nt be too hard to track down. Sorry I couldn't have been more help and I hope this points you in the right direction.
