OC'ing isn't difficult but it does take a couple days of research before you do it the first time.
There are lots of good threads here about oc'ing AMD and INTEL systems; you should be able to find what you need.
The bottom line is that pretty much any video card and cpu out today can be ran 10% to 20% faster without any problems... so why not get your *free* 10%? There are always risks though and you shouldn't assume your system can do what someone else's can. Lots of the hardcore oc'ers try cpu after cpu after cpu until they get a winner.
