So I have an ATI 4890 as my primary display adaptor, using it for 3D games and the like. I have a 7600gt that I would like to use for 2nd and 3rd monitor, but when I ran the installer for the NVidia drivers the computer BSOD saying something about the driver mismanaging something or other. Is there some trick to get ATI and NVidia cards to work on the same machine?
