What? No. In 2009 Intel was using socket 1366 for their i7s. If you have one of those and want to upgrade even to a 2-gen-old Sandy Bridge CPU, you gotta replace the entire motherboard and RAM (unless you were lucky enough to get a dual channel kit that runs <=1.5v). AMD users have it slightly better in that their old RAM might still work, but they still need a new motherboard. Hell, if you built an Intel build before this month, you’re now looking at another new motherboard to get a Haswell chip.
