You could probably get a Z77 mobo and an i-2500K on the cheap nowadays and with a decent overclock you can play most titles at full speed (thats what I have). If you can find a newer processor for the same price go for it just make sure it is a K series so you can overclock and I would stay away from AMD processors. Since that power supply can run your 770 without issue you may be able to get away with using it in the upgraded rig.
Correction: at newegg the Haswells are only $20 more than the Ivys so go with something like this:

As long as your RAM isnt ancient it should work with the new mobo above. total cost (ish) $350 for a kick ass system. You, of course, need to do the homework to ensure all your parts are compatible, etc but I wanted to give a little insight.
