I am concerned about the whole bent pin processor issue that was brought up about 2/3 of the way down this thread. Sounds to me like you have more problems with your build than are relating here. What else did you completely screw up when you assembled your rig? I am beginning to see the problem, and I think its between the keyboard and the chair.
Ouch, it was a prebuilt rig I decided to upgrade - big mistake. If I had the money, I would build. The only thing is the CPU that got fucked up. My concern is the GPU, I doubt the CPU is still or most likely, my rig won't be functioning correctly. The only thing thats not is the GPU. My last score on furmark was a little under 600 but that was with all my applications open. Before that, it was with everyone else around 900 - 1100. If its worth it, I'll probably build but I doubt I'll get much better performance, the only other main thing I'd change is the CPU to an i5 2500k but my motherboard isn't compatible with it (Asus M4N68T-M V2).
Watch your language!
