Actually temps were lower while I was playing TF2 than while I was running artifact scan.
I have the X2, I just haven't opened it yet. 60'C idle isn't that low, considering I'm idling at 45'C with the stock cooler.
So. Was it a mistake to buy the X2 then, if there's not much point modding it?
Mine came out of the box at 581/702, isn't stock 580/700? Not much of an overclock.
