I agree ATX motherboard. 

use a ATX motherboard and look at getting a gtx 760 or 960 instead of a 750ti

:)

Looks good, but ATX mobo + too high wattage a PSU even if planning to upgrade + if you can get something like a gtx 950/960

I agree with what has already been said. A full ATX motherboard adds room for expansion and a higher end GFX card allows for better performance in more games. A 750 watt PSU is a bit overkill, but I can't tell you that(I'm using a 1200 watt PSU for a pc that draws 400).

i would go amd because it a lot cheaper and get a lower watt psu

Take a look at the ASRock H97 Anniversary ATX for the Motherboard and the EVGA GeForce GTX 960 2GB for the GPU. It's just a thought.
