Just about to but a new core 2 cpu, I have been waiting for the price drop, now that its here I would like to know,reading by the specs, if the E6420 will give me the same performance of the E6600, the only difference that I can see is the E6420 stock speed is 2.13GHz and the E6600 is 2.40GHz, both have the 4mb cache,I will be overclocking so is there much difference in performance between the 2? trying to hold of buying the Motherboard to the DFI Infinity P965-s is released.
