I have an SD FX55 and I can get 3.5Ghz out of her with core voltage set to 1.7v, scorchio can do the same so deffo over 3.3Ghz providing your motherboard can provide the juice it needs.
Volts set as per my sig 1.475v to the core then set special VID control to 113% - My DFI drops a few voltage points along the way but that gives you the best voltage option and maxmises the overclock.
Of course if you have an ASUS mobo you may be limited to 1.6v in that case 3.2 or 3.3Ghz can be expected.
