Unless you have programs (say, a video editor/recorder or hardcore games) that can make use of the 6 cores, you won't see any performance improvement. Actually, AMD CPU's have shown to actually be WORSE than their Intel 2- and 4-core counterparts at everyday tasks other than heavy-duty programs. Just because AMD cores have more raw clock speed doesn't mean more performance over the design shortfalls that they have.
As for overclocking; If you had heat problems at stock frequencies It's not a good idea to go OC'ing it until you have your heat FULLY under control. Riider already covered the heat sink and thermal paste.
