Her ya go this is my set up.
XP PRO
Soyo P4 FIRE Dragon(Im not a soyo fan But this is a great board)
P4 2.2 GZ
2GB RAM
160 GB UDMA 133 HD
40 GB SCSI 2
NVIDA GFORCE 4 WITH 128 MG RAM (TI MODEL)
VIEWSONIC 21
2 CD BURNERS AND 1 DVD ROM AND 1 40X ROM

There was a catch to get mine running since i have a g2 upgrade from deluxe.I had to install deluxe with only 1 addon,then install g2 and install all the rest of the upgrade addons with the patch,then i had to install g2.Right now with every slider in g2 over to max my frame rate is 76 fps.
It is possible with xp.
Hope this incurages you to upgrade to Xp...........
