not much choice if you want an OCable CPU on intel's side. i really can't recommend a 2500k this far into the year. no offense, it's still a fine choice, but only if you're living at a place where your choice is limited or it fits perfectly within your tight budget.
if you're not at all a big OCing kinda guy, the 3470 is a good option for the price. at least you saved up a bit to bring your plan to upgrade to a 660 (or maybe more) that much closer.
All right 3470 it is! Thank you both for your time!
