No, it won't in a general sense. The 380x/280x is the highest end GPU that should be paired with a a10/860k CPU.
The long answer, the CPU can bottleneck in some titles, such as ARMA/ DAY Z/ GTA V.
Whereas the GPU can bottleneck in other titles that are GPU intensive.
So there isn't just a single answer.
On average, they are a good match.
Don't buy into the bottleneck argument, if you are using a 60hz monitor and you can play your games at around 60fps, then the world is fine.
