Just a quick question from a newbie, wouldn't the recently released 6870 IceQ X Turbo in Crossfire be a great choice of the Luxury System as well? I mean it compared with the 6990 and 590 while being around the price of the 580. From what I've read it does take up more power than the 570, but is quite cooler. Am I missing something? Or is the $200 gap worth the performance gain?
