Ok. I got the 9590.. wish i hadn't but can't go back now. I have a Gigabyte 990fxa-ud3 Mobo and a Cooler Master Seidon 120v Watercooler on it. I ran a OCC stress test on it and it came out at 62 C after 3 minutes. I don't know if thats good or bad seems to be a little high. My problem is that after playing some games (mainly cod advanced warfare) My PC will freeze up. sometimes sooner than later. just trying to figure out why.
