If you play a poorly written game which places undue load on the CPU, then it will be the "bottleneck".
With most games, your CPU should be fine. Very few games have big benefit from an i7 or clock speed above 4Ghz

But please bear in mind that something in your PC is always the bottleneck, whether it is CPU, cache memory, GPU, RAM or HDD, your computer is always waiting for something to complete it's process.

Not enough to worry about, especially at 4k

At 4k your ok, 1440p @ >100fps would have been more of an issue

Thanks for all of the answers. Just dropped ~600usd on the evga 1080 and will be able to sleep tonight knowing I don't really need a new mobo,cpui,ddr4 taboot! cheers

@4K most Intel Core series CPUs i5/i7 will not bottleneck even the fastest of GPUs. I run 2 GTX 1080s with a i7 3930K @4.2ghz with zero bottlenecking issues. It's when you game at 1080P/1440P AND at frame rates >100FPS you have trouble. If your a 60-90hz gamer even at those resolutions you wouldn't be bottlenecked assuming your gaming at max settings and max filtering/AA (16x by 8x). Anytime you tax you GPU harder your CPU needs less juice to keep up. So whether you raise the resolution, you raise the graphics setting like I mentioned or both, you give your CPU more breathing room. Now there are exceptions as mentioned. BF1 for example can floor any i5, especially in multiplayer. More and more games can take as many threads as you can throw at them. However for the time being your are good and should not stress CPU bottlenecks with any GPU on the market.
