As long as you find good drivers for it, the V5 is still a very formidable card. I have one in WinXP myself, i forget which drivers i'm using but i'm sure a quick serach in the Video forum here can lead you in the right direction. The key is to find a set that still supports OpenGL, FSAA, and all the goodies. Personally i kept searching till i could use 3dfx tools again.
