Yes, especially with a decent HSF, you can OC the CPU to at least 3.3 GHz.
I have no clue about overclocking, do you think you could suggest a good guide?
Also, how much hotter does it get when you overclock? My computer is never too warm, the air blowing out the back of the power supply is warm, but the air blowing out of the system is between cool and warm. If I OCed do you think i would have to find a way to make it cooler?
