Ok, My HEATSINK WAS NOT IN PLACE! I fixed it...but heres the question its ran a good few hours...everything seems to be fine, is their damage or?
Unlikely. I believe you have to run it that hot for a very
extended period for damage to occur. It should be fine. If you really want to be sure though, you could always run a stability test on it. Prime95 or linx are good.
As for the PSU being a problem, if that were the case, your computer would not work or would shut down on load. Not a framerate drop.
