Not bad, but I'd nix the EVGA ACX, which they put crap parts on, and go any other reputable brand of 970 or non ACX EVGA. Best IMO is the Giga, and NCIX have it in stock. I'd also drop the RAM to 8GB to afford it.

Optionally, if you want to get a bit better HDD, the WD Black is very good. You could also upgrade to the ASUS Sabertooth Mark2 MB, which is about $25 more and has a standard 1866 MHz RAM speed vs 1600 (no OC), DTS capable onboard sound (via pass through), and a 5 yr warranty.
The sad thing here is in a little over a year, there will be MUCH better parts to build with across the board, from Pascal, to 1151, to Skylake, to DDR4. 2016 will be a far better time to build.
