Just had a question for you guys. ATM I have 2 monitors hooked up to my 8800 gt. Would it be better to put my old 7900 in a second slot and hook one of my monitors to that for performance? I was thinking 2 wow instances on the 7900, and 3 on the 8800. Would that make any difference in performance/fps, or do I not have a clue what I am talking about?

Btw my motherboard doesn't support sli.
