ive got a i7 950 @ 3.2GHz and even when i used stock cooler it was rather cool. under 45C load.
under 40C now.
is your case getting decent air movement through it?
im running nearly the same system. main diff is video. i have a radeon 5770. it does well. i play mostly starcraft II lately and its on max settings doing great. ill upgrade to the 7k series come late this year or early next when the better model numbers come out.
im also using 3 27" monitors. its ok with nearly maxed settings on shooter games.
the cpu is rock solid though. I have ran WOW, Starcraft II, Dragon Age 2, Netflix, Pandora, Avatar blu-ray, Sherlock Holmes blu-ray rip, a Hulu.com movie, and a AVG scan at the same time, all that got the processor up to 60% usage.
