Yes sufficient, will do very well. I run 1440 144Hz on a 2080 Super and achieve over 120fps in games I play. Some more demanding games need settings to be a mixture of medium/high/ultra to achieve this. The 2080 Super isn’t significantly faster than a 2070 Super so I’m sure it can give a good gaming experience as long as you don’t have expectations of maxing out all game settings.
What speed is your RAM and is it 2x8gb?
A 3600 is more than enough. The gpu will be the limiting factor before the cpu in AAA demanding games.
RAM speed can reduce FPS but at 1440p I’d expect the difference to be less than at say 1080p. How much will be different from one game to the next. In my view it would not be worth changing. 32GB is overkill. My main concern is if you were only running 1x16gb as single channel can have a significant impact on FPS and stuttering.I'm more than willing to play on lower than ultra or play with the settings to get solid performance.
I believe the RAM has up to 2666MHz and it is 2x8gb. 32gb would be overkill, no? Also, how much does RAM speed affect performance? Would it be worth it to upgrade to a, say 3600MHz speed RAM?
