I'm using a ViperII, you can find them for under $100 now.
It plays all the games I have very well(Q3A, UT, Starcraft, Icewind Dale, Diablo I & II...) and plays DVD's very well also. 2D image quality very good also, not as good as a G400, but close.
It runs fine on my system with the latest drivers. You can probably forget about any future releases of drivers since S3 sold out. But mine runs great and I haven't any problems with any of the games or applications that I run.
