Don't see a power supply listed. Make sure to get yourself a quality unit, tier 1 or 2. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
AMD RX 480 will be out, by the end of the month. AMD is claiming R9 390 performance, for $200. Right now is simply a bad time to buy a GPU. The Cryorig H7 is a better cooler, for only $5 more. What kind of budget do you have? You may be able to get a much better graphics card, if you drop the overclocking.
