So I've done quite a bit of research on this, and here's my idea. I upgraded my old ATI card to a 5770 so that I could run FCPX. Did the upgrade, everything worked great. I have since decided to add a third monitor since I thought it would be as easy as just plugging it in, but obviously that's not the case. I'm trying to avoid buying those $100 DVI adapters, so I'm wondering if I can just throw my old ATI card back in to run the third monitor on it's own. Possible, or not?
