^^^I do agree that he should replace the psu, but no way your gonna be playing at 120 fps to match that 120hz in most games though, 1080p and 60hz with a low response time is the bet single monitor configuration a gamer can hope for unless your going to spend over 1 k on an led or higher res monitor but I would say that crossfire 6950s would benefit a single 1080p display a lot into the future, thats a lot of gpu muscle...
