So I have previously changed my CPU, PSU and GPU but I never built a PC from scratch , I have an idea of what its like to build a PC but what I need help with is some advice about the components i'm using ( http://pcpartpicker.com/p/2kHba )

My original budget was £700 but when I put the list together it changed to £800 but now it is over a £1000! I don't think I would have the money to buy that if all im going to use it for is gaming (Dayz, BF4, rust e.t.c) I know AMD and ATI is cheaper but since I am a Nvidia and Intel fanboy. Any suggestions about the parts, anything you would change?
