I'm trying to build a new gaming PC and i was practically ready to choose between one of these:

  1. i9-9900k & RTX 2080 Ti
  2. i7-9700k & RTX 2080 Super

But then i read about something called "CPU bottleneck" and in some reddit thread they mentioned that it's especially affecting 1080p resolution.
I am playing & streaming league of legends at 1080p with 240 Hz (FPS capped at 240).

I want to have a strong enough PC to handle new titles but 70% of the time i spend gaming is pretty much League at 1080p & 240 Hz, so i am not willing to sacrifice performance in league (especially that it's my main streaming content).

Would i experience any sort of issues running 1080p & 240 Hz league with those 2 setups?

It almost makes no sense to me considering i am pretty much running a less demanding resolution, so it should be easier on both CPU and GPU, right? So why would there be any bottlenecks?
