What cpu bottlenecks actually DO in games.

Okay, this is some pretty muddy water as far as I've seen, and I don't think I've seen anyone explain this clearly. What I understand from everything I've seen, the cpu gives you a frame cap and up to that IT DOESN'T MATTER (well you can get like an extra 2fps in most cases). The fx-6300 gives a cap of about 146fps on bf4(using 4/6 cores) (which is known as one of the most cpu intensive games) and that is more than you need for gaming in nvidia active 3d while a single 980 can get up to 90fps in 1080p and ultra settings. So, am I missing something here or are all of the arguments over bottlenecks useless?

A CPU bottleneck is where the CPU is running at it's maximum performance with all cores at 100% and the rest of the system, usually the GPU, is running only at a fraction of its usage. Whether it be 50% 75% or 80% with the CPU running at 100% the GPU or other components can not run at there maximum. This is a bottleneck.

Example: Take my gaming system which is no slouch but needs a better CPU. In Guild Wars 2 my CPU will run at 100% on all cores and my GPU only runs at 55% with a FPS averaging between 40 and 75. When there is a large battle I go as low as 6 FPS. This is a bottleneck. Once you reach the maximum performance of one part it holds back the performance of everything else.

once you reach 60 FPS and can maintain that on a 60 Hz monitor having a bottleneck over this is meaningless. If you can not hold 120 FPS on a 120 Hz monitor and when you have a situation like I do in my example then the bottleneck is a concern.
