Your comp. will probably not support two video cards at once. What you CAN probably do is find a Video card and (or) an OS that can or will project to multiple monitors. In direct response, though, I don't believe it will support two video cards at once, you CAN always try though. Nothing inherently bad could happen out of it, and even if it did, I could probably talk you through it. Anyway, I hope this answered your question.
