the gpu is r9 280x 3gb
cpu: amd fx 8350
cpu cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler/ cause the stock cooler is shit

ram: 8gb 1600 mhz corsair dominator ram
case:Fractal Design Define R4 w/Window (Titanium Grey) ATX Mid Tower Case

this would be a great build espicially with mantle comes out soon. i put the 750 watt psu so you can at least crossfire in future and the case looks really good.
