Almost all overclockers talk about setting up ther core voltage but I also have a another setting vcc3 set at 3.3 which I can adjust manually as well. what does this do and should I be messing with it.

That is the V I/O voltage. It sets the voltage to the ram and buses. It often helps to run around 3.5v for some video cards. V I/O has proven to be critical of going too high, and may cause instability in itself if you go much above 3.5-3.6v.
