Going from 1080p to 1440p you should have about the same FPS unless the video card can't process that many at the higher resolution since you said a i7 2600.What about bottleneck with my configuration? i would have same fps as 10700k/10900k owner with rtx 2080, and on 1440p i would lose ~50fps
Your cpu could be the limiting factor in some games and no you won’t achieve the same FPS as a new 10700k. However it will still be a good gaming experience.What about bottleneck with my configuration? i would have same fps as 10700k/10900k owner with rtx 2080, and on 1440p i would lose ~50fps
