i am sure its been asked before but i cant seem to find a whole bunch of direct answers to the main question. i have a few hundred quid to spend and i have a D820 at the moment. i know that any C2D will destroy it and because of that i just put in a new DS3 mobo and 2gb of geil 6400 ram. so simply which chip is better overall? the 6300 or the 6400. i have seen some say that the 6400 clocks better, some say that the 6300 clocks better. with the price difference of only £37 ish which one is actualy the better core to get?
