There is something here that many are missing...
We pair a 4 year old architecture with an almost last gen vga (980ti)...
I am wondering why AMD hasn't discontinue the production of the FX line instead of getting so much bashing...Clear out the retail channel and mainboards and discontinue.Relocate the resources to Zen...
On the other hand maybe removing yourself completly from CPU consumer market may have been a even worse case scenario ?
There is a review where even a 2500k is bottlenecking a gtx 1070

There is an arrow pointing down in the first graph where 2500k is pitted against 6700k and you will see that Star wars battlefront and Xcom 2 on 1070 are very bottlenecked by 2500k ...
So as older as cpu architecture is the more bottlenecks you will see with newer cards...With 2500k you see less bottlenecks but they will be more and more...Seems for 2500k the max card without bottleneck is gtx 980 ... Upp from that you get axed..

The "unlucky" FX series was crippled from the beggining in some design choices so after so many years it looks worse in the eyes of many...
