I have a QX6700 clocked at 3.4 running 4 gig of ram on windows 7 64 giving me good speeds in all apps etc, but I've got this need to update to a decent i5 system that i don't think i need.All review sites compare the two at stock speeds but i need somebody to tell me that the processor i have is more than adequate and i will not see any vast improvements in every day applications
