. I'm buying a i7-4790K and a GTX 960 and the CPU bottlenecks just a tad (not very big amount). So , I would think it would bottleneck. I had a FX-8350 and a GTX 960 at one point , and a R9 390 is a lot more expensive and more powerful . With the GTX 960 , it bottlenecked a bit (is bottlenecked a word?) , so with more expensive equipment comes more bottlenecking (also a word?) Therefore I would recommend a FX-9---- or a Core i5 or i7.
