Im saving up for a "bragging rights" gaming machine, money is not an issue but I would like to get 2 maybe 3 of these in sli. But im worried about heat, im getting an amazing case "Haf 942 x" so I will have great air cooling but still I hear the stock cards run hot, and these are superclocked so im a tad bit worried...anybody have the info I need? I just dont want to fork out 6000$ if they will burn out soon after purchase, I plain on playing games like dirt, starcraft 2, crisis, and world of warcraft which I usually play that for about 6hrs or so straight, but im not worried about that cause wow is more cpu which is why im going 980x OC to 4.4ghz with digital storms frostchill liquid cooling from swiftech.
