R9 390- Crossfire r9 390s are about the same if not better than a 980 ti. And AMD is supposedly going to have larger performance increases in DX12 :P They were also cheaper. i5 6600k- good for gaming. Cooler Master Hyper 212 EVO- cheap, and good performance
This is my first build, and pcpartpicker helped a lot. I will be using this pc for gaming alone probably.
