So I'm building a new gaming pc, and I'm looking for a graphics card. The R9 270x I was looking at before is out of stock unfortunately, so I need to find a new one. I have an AMD 6300 chipset and I want a card under $180 tops. I also want to be able to play games like GTAV or Fallout 4 on at least 40FPS, no ultra settings. Any suggestions?
