seriously, why are you upgrading?
I would overclock your cpu.. and if you are the kinda guy that needs the latest and greatest, get a new graphics card. what games are you playing that require an upgrade? or are you just upgrading to upgrade?
If you want the best that money can buy, wait till later this year - the new platform that runs DDR4 is coming out in a few short months... and nothing that is currently available to the public will be able to compete.
