I had an R9-270x paired with 8gb ram at 1600mhz and a A10-5700 CPU. I averaged 60fps on BF3 with a mix of High and Ultra settings (AA turned off, AFx16). However, the frames fluctuated considerably and would drop in low to mid 40s. I would play Titanfall on High settings with AA turned off and bilinear AF and got 55fps to 60fps on 1080p gaming. The GPU is great,, especially when you Crossfire two of them (like I did)! But i7 baby is right, it depends on your CPU to push the 270x.
