Help with my first gaming PC build

Solution
Any reason for going with windows 8 pro over windows 8.1 (non-pro)? If I were you, I would try to squeeze a gtx 780 into that build, especially since you are going to be gaming at 1440p. Also you will not notice the difference between 1600 Mhz ram (CL 9) and 2400 Mhz ram (CL 11), last time I calculated the difference it was something like 2 nano seconds. You can probably find some 1886 cl 9 ram for a bit less and would actually be about the same as the 2400mhz cl 11 ram
