I was thinking of upgrading to either the 6870 or the 6950 but am not sure on which to choose. I haven't been able to find a 6950 to buy so if you guys could recommend any websites which are safe and reliable, that would be greatly appreciated. I am going to buy a Corsair Enthusiast 650W PSU to power either of the cards. I am hoping to be able to play games like Skyrim, BF3 and Farcry 3 at medium or high settings depending on whether I get 35+ fps or preferably 45+fps. One more thing; would my i3 2100 be capable of handling these cards?
