Re: You may think I'm nuts, but processor upgrade to new .45 Quad makes a major differenc
Yep that could be the reason. most likely you were held back by some apps in the background with the E6750 & now with the more cores you are running as you should.
i did a test myself for the CPU test on a E6700(2.66Ghz) , recoreded the score & then installed the Q6600(2.4Ghz) the score was a little less due to frequency difference then to make sure i ran Prime95 on 1 core & Toast on the second core & let the other 2 cores to handle Crysis CPU benchmark. guess what ? same score .. nothing changed.
