i know there are conroe chips with 2mb and 4mb cache's, im jst wondering if there will be a big performance difference between the E6600/E6700 and the E6300/E6400 just because of the cache size?
Anandtech did tests on it. There was only an average of 3.5% difference, with 10% being the highest and that was with DivX. I don't know if those included games, but you definitally wouldn't notice in games.
