Yeah. The C2D are great for Overclocking. There is a bunch of shit on OC C2D if you google it. Plus like FA said, ppl on the forums should be able to help you out. I haven't OC'd mine yet either. Planning on it though. I've the C2D 6300. Which I've read people have OC'd to 3.5ghz/4ghz. Depending on your heatsink.
This new processor is amazing though.

FA told me to wait... I fucking hate waiting. :p
