I recently bought an ATi Radeon VE 32mb
I have been a bit disappointed with its Win2k proformence, but the problems are small really.
The quality while playing movies is the best I have seen on any video card. I am very, very impressed that my DVDs look sharper than ever.
Gameplaywise its been fine... nothing that blew away my old Voodoo3 but I think its a notch better than it. If you're keen on getting the best graphics go MX, if you don't care about graphics at all go Matrox. If you watch a lot of movies and play some games go ATi.
