The idea is this being a budget build to get your foot in the door. Room for upgrading later, with the AM3+ Motherboard and 2x PCI-e. Not sure if 500w can run dual 7770's but this is what I can work with budget wise, unfortunately. I was considering the Rosewell 630W PSU Green series on Newegg for the same price as the Corsair CX500W but I have trust issues.
If you notice any inconsistencies, feel free to point them out. Such as incompatibility and the like.
Just a tip if anyone's going to copy this build. Swap the G.Skill Sniper 9gb 1866mhz for G.Skill Ripjaws X 8gb 1600mhz. CPU + Motherboard combo can't run 1866. Only on AM3+ like Bulldozer and Piledriver.
