Heyy in in the same boat and am trying to upgrade mine. How much did it cost for those cards? I want the 580 gtx too & in SLI. I got in an accident and idk if I'm fit to do it myself an plus I don't know what I'm doing (if only I was as good w/hardware as I was software)...so should I just call Alienware and have them out it I. For me?
