Will this GPU bottleneck the 8th generation CPUs; specifically the i5-8600K?
That all depends on the game and graphical settings. There is not a blanket answer to this. Bottlenecking all depends on the game and graphical settings and any CPU can bottleneck any GPU under the right circumstances. Bottlenecking is not a absolute thing or a yes or no thing like it is made out to be.
Also it is 100% meaningless to even think about provided you chose your parts right and get what you want. You should chose the CPU for the FPS you want and the GPU(s) for the graphical performance you want. If you are happy with what you get and meet your goals then why worry about something that is not impacting you?
