Any compatibility issues?

You are wasting a hell of a lot of money there....

If this is strictly gaming build, get a 256gb 950pro m.2 for the OS and then two 850 evo 1tb, you'll save ~$400 and still have maximum game loading performance.

Also, I hope you aren't going to be using one of those lame gaming headsets with that sound card, that would make it a waste of money!

There are compatibility issues with the M.2 SSD. I wanna try to fully maximise the 165Hz monitor. So only the storage is off. I will use the sound card along with my Audio Technica ATH-AD700X. Anything else that is overkill?
