Personally, don't OC unless you need it.  OCing does void the warranty, it reduces the chip's lifespan, and, as said, can cause overheating or destroy the chip (last one is unlikely if you do things properly though).  Personally, my Q6600 is way faster than the amount of power I need, so I don't OC.
