I currently have an AMD Athlon 64 X2 Dual Core 4800+ 2.40GHz (Socket 939) CPU, and shall probably be getting a Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz (1066FSB). How much of a boost in performance shall i get from the new intel cpu if i dont overclock it, as they are both the same speed, 2.4GHz?
