you'd be more than perfect with an i5 haswell 4670k, No need for i7 4770k but if you have the cash i can't stop you. I'd only get an i7 if i was going to be doing extreme editing photos and video.
If your sticking with the prodigy, There are some good mini-itx boards something to think about.
yes that is very true and i know i dont realy need the i7 but just to get max out of my system and maybe in a year grab a new case and mobo to sling another 770 in there when the games start getting intense
