@SLo_STi - Saskatchewan is a little far for me to lug my entire gaming rig.
@ulimatt - Why?! WoW/SWTOR/LoL/D3 - What else do I need?
@harrymonster - I have a 2600k w/ an H70, and using the "OC Tuner" option in the bios, it OC's to 4.4GHz. I haven't bothered going past that, as I don't need it, but it's fairly easy. You can find guides that essential run down what you need. Start low, work your way up till it crashes, then just slightly pull back. Typically you start turning up the multiplier. Then when it's unstable, you turn up the voltage a little. Then more multipler, etc. I've never bothered with RAM timings, so don't even ask haha.
