Agree with above,
Switch down to a 4690k (i5) and switch the GPU for something better (GTX 770 is an option, look at the build I recommended lemon)
Atm you are going for a tiny case and motherboard, is this intentional?
Also, you don't need a 750W PSU, corsair is a good brand, but CX is their cheapest crap. There should be a 600W seasonic?
You'll also need a decent CPU cooler, the intel stock is shit. Go for a corsair H80i or w/e closed loop watercooling they offer (only decent thing that will fit in that tiny case).
And 16GB of RAM is overkill, 8 is more than enough for games.
