The only thing I'll say is the OC'ing is 50% luck and 50% precaution. The 50% luck will piss you off beyond belief, so be ready for frustration. It all depends on if your parts are designed for OC'ing, and if they are, if they're actually up to the task. I'd post a guide on OC'ing since I have a lot of experience, but the actual task annoys me so much that I think I won't.

Half the time, once you get a nice OC going, games freeze and then you have to clock it down some MHz by MHz. UGH that makes me wanna go crazy.
