I'm interested in upgrading my 2 GTX 580's superclocked (1.5GB), and get 2 GTX 780's FTW wit ACX cooler. I was wondering if anybody know's if my rig can handle those cards. My rig is an Alienware Area 51 purchased in 2010. It has a 1.2 kilowatt power supply, Intel I7 930(2.8GHz, 8MB cache), 12GB of ram at 1600MHz, motherboard is original(X58 I believe, if that sounds right) and running triple monitors. Not much of a computer wiz just know enough to get by. Any help would be greatly appreciated. Thank you.
