The i7 does not show any advantage over the i5 at this time and getting the i5 would let you fit the gtx 770 into your budget.

If you are adamant about the i7:

Put a cooler in the second build for overclocking but if you don't plan to overclock or are unsure at this time you can take it out.

Edit: also you could drop the SSD and fit the gtx 770 into the i7 build
 




If neither build is going to use higher memory than 1600, why even go with a Z87 board and K series processor? Not a dig, just curious.
 


Mainly for overclocking. Ram, gpu, cpu could be overclocked. Only the Z87 mobos and k processors allow for overclocking of the CPU.

Edit: I do recall seeing some 1866 ram for only a few $ more so that would also be an option.
