I recently upgraded to the 2070 Super with a 2500k, time for a CPU upgrade!, the 2500k just isn't cutting it with this card,
Rough. I did the same upgrade (980Ti to 2070 Super), on a 4770K and my FPS increased by 48% at 3440x1440 in Assassins Creed Origins benchmark (39 -> 58). Funny, that's EXACTLY the expected effective speed difference on UserBenchmark.
