I'm heading in the direction of a three monitor set up and hence suspect I need to go the dual video card route. At the moment, I've a Radeon X1900GT driving two 19" monitors which I'd like to keep and augment with something like a Radeon 5570 which would drive a 22" display.

As such, I'm just wondering how Catalyst will cope with this configuration and whether there are any other issues that I'm likely to encounter. In terms of the obvious, my motherboard has two PCI-E slots and my power supply has two video card power connectors, so I'm hopefully covered from that side of things.

Thanks in advance.
