Getting ready to upgrade a fairly new system from XP to 7. Currently I have a Radeon 4670 PCI-express as the main video card, as well as an older nvidia card in a regular PCI slot (because of a few older games that won't cooperate with PCI-e). Each card runs on its own monitor, and I just switch the primary (in display properties) when I run one of the older games. This whole setup runs fine. However, the nvidia card does not have any Win7 64bit drivers available, so I'm going to pick up a cheap PCI nvidia card that does (looking at the geforce 6000 series) which does have the driver support that I need. But before I go and buy it, I want to make sure, can this still be done in Windows 7? I've heard that now multiple video cards have to use the same driver, I don't know if that's true. There's no problem at all with this setup in XP. Any help would be appreciated!
