The FX 8320 will definitely not bottleneck a 7970, overclocked or not. The GPU will also work fine with that motherboard.

Your power supply has 42A on the 12v rail, and the 7970 draws about 300 watts at load. You will be fine. On the other hand, the R9 270x won't draw more than 150 watts, saving much more power.

get the r9 280x, they are basically the same card just the r9 280x is newer with some tweaks, it also has AMD's mantle. and the price is about the same
