There's always a bottleneck somewhere in a build. I paired a 970 with a 12600k and it worked fine even though the 970 bottlenecked the 12600k. People need to end there obsession with bottlenecking. Don't worry about it unless your performance is bad.

Generally speaking you want the most expensive part of your build to be the bottleneck.
