The one I had @ 4.2 GHz was starting to show some minor bottleneck with a Sapphire R9-280 (non-X) in the game benchmarks I ran. Same with my Evga GTX 960 FTW. So, you'll have to put up with some bottleneck in CPU limited games with the R9-280X. But it's not a deal breaker IMO. Btw, your build lists a 280, not a 280X.
The 860k will absolutely bottleneck a 280x in cpu intensive games.
The other problem is that your 860k is non-upgradeable. the 860k is the best cpu they make for FM2 motherboards and it is not on par with a middle-of-the-road CPU like the fx-6300 or core i3.
When paired with mid range GPU like 280, the 860k will give you same results in GPU intensive games like the most expensive i7. Considering how cheap it is, it might be the best option for budget gaming PC.

What a bogus claim, the single thread performance of an i7 (or even i3) is going to beat out the 860k for non-cpu demanding games, thus you will notice the difference in anything that could be classified as "GPU-Intensive; sure something not stressing the system will run close to the same on both systems. Now when you talk about cpu-demanding games, it is not even fair to compare the two.

You are confusing the gaming power of a cpu and a gpu's ability to render detail .
You are also confusing single thread performance with the total computational ability of a processor . Something that is largely irrelevant with newer game engines that can run multiple threads simultaneously

Lol but no, I have it Paired with the XFX R9 280x I get 60-80FPS Ultra settings in Starwars battlefront, I overclocked the CPU to 4.3GHz and its great I get 100%GPU Usage and everything
