Yeah your mobo and cpu are fine for sure, maybe slap a 3rd party heatsink on your cpu and overclock it (if you haven't already that is) after all; that's what the 'K' processors are for. I'd wait for nvidia to bring out a new range of cards which in turn will drive the price down for the old cards, then you'll be able to pick up something like a gtx 970 for a decent price.
