Hi guys, I am hitting a wall here. I have a single monitor pushing 1920x1200 I am looking at purchasing dual 6970's for xfire. Is this a waste of money or will I see great performance gains? I am not going to drop in triple monitors at the moment as I am playing with the wife's budget constraints she has set for me. I have found endless information on 6970's with tri-monitor but none for a single.
