I know this is an old thread and you've probably already upgraded, but for the sake of others with a similar question, maybe you could find a used i7 970 or 980. They're hexa cores and the 2 extra cores would probably be enough of an upgrade to not need a new motherboard because they're the same socket type. on ebay they're about $220-$250, so about the same price as today's i5's. They're also the 975, 980x, and 990x if you want to overclock a couple hundred more mhz
I also have an old Intel Core i7 970 3.2GHz, LGA1366 and want to build a new machine.
What is the latest & greatest stuff?
I'm just starting to research today for the 1st time since 2011...
What have I missed or better, where are we now?
