So what with gtx 1080 ? This gpu do bottleneck with my cpu ?
You'll probably still have a very minor bottleneck even with that card. However like I said above, don't worry about it. There are two types of bottlenecking, 1. Bottlenecking that doesn't affect game performance noticeably. and 2. Bottlenecking that does affect gameplay.
Your in the #1 category. You'll be fine.
Also, bottlenecking depends on the game. Most of the time you shouldn't get a bottleneck but on some CPU demanding games there will be a small bit.
