I've got an Nvidia Geforce 9500GT and am thinking of buying an ATI Radeon HD 4850. I have two PCI-Express slots. Would I be able to run these cards simultaneously on Windows 7? I want to also be able to use 4 monitors.
I've checked online and found plenty of SLI and Crossfire tutorials, and plenty of driver issue warnings, but no definitive answer.
Would it be as easy as putting in the new card and installing the drivers (assuming also my PSU can support both)?

As long as those graphics cards have WDDM 1.1 compatible display drivers you shouldn't have a problem in Windows 7 (in theory that is). Previous versions of Windows e.g. Vista, required you use graphics cards from the same manufacturer with the same driver.
If you can make do with 3 monitors you could get a Radeon HD 5770 which offers the same or better performance as the Radeon HD 4850. SLI and CrossFire are irrelevant in both cases.
