Hi!Imgoing to buyna quad for mySystem ( rampage formula x48) and i have this options A q9400 at 280 dollars or a C1 q9550 at 350 dollars. In my country the e0 revision of q9550 havemt appeared yet Both cpu would be clpcked at about 3,8 ghz. I have seen some reviews comparing q9400 and q9450and i high res gaming they performed about the same, so i think that the extra cache is useful. What dp you think? Is worth topay the extra money for a C1 q9550??
