Well the R9-270 has basically the same performance as a HD 7870. So here are some benchmarks.

The R9-270 will be able to get 60+ FPS in any game on low. It just depends where you put the graphics setting.
And just realize if you do go with AMD, all their 6 and 8 cores have about the same performance, so there's really no possible CPU upgrades.
