Playing on 60FPS for 1080p/1440p? titles like Odyssey, Crysis 3, Battlefield V, RDR2?
Agree with @MrN1ce9uy . Getting the RTX-2060 will definitely help you hit the 60FPS mark at 1080p. Might have to turn down some settings for 60FPS 1440p, but should be doable.
Depends what you are aiming for. BFV multiplayer and RDR2 are going to struggle to average 60 FPS due to the cpu regardless of gpu. How much of a problem this is depends on what you want.
