Now I am about to buy one of these chips but I have heard rumours... The rumour is that e6400's are overclocking further then e6600's because the extra cache could possibly be holding them back. Accross a lot of forums the e6400 is being recommended as a better overclocker as apparently a lot of 6600's cannot reach fsb 400 and run 1:1 ram but 6400's can quiet easily get 400fsb and run 1:1 ram @ 3.2ghz (8x400). Basically, can anyone confirm or deny these results with evidence? If the 6400 is a better overclocker, i can see NO reason to buy a 6600, as the cache does not make a sizeable difference in todays applications and ill just get a quad core in a year anyway Cheers.
