[SOLVED] Impact of increase in resolution and refresh rate on performance. 1440p 60hz vs 1080p 144hz whats more stress for GPU?

[Lieto]

Greetings,

I am looking for 24/27 inch gaming monitor and i am bit confused.
I have a 2070rtx 4690k 1080p 60hz setup and it allows me to run the game i am currently playing (Black Desert) at "very high" settings above 60fps at all times (it's not a super optimised and thus fairly taxing game i dont think i could run it with stable 150fps with these settings).

I was thinking to go 144hz 1080p since you know, gaming. But i keep reading that increase in hertz "doesnt hurt performance because its the frames your card is producing anyway" — Really? I mean you need a beast of a setup to run modern games never dipping below 150fps at max settings dont you? I would even argue that having a requirement to run double the fps must be more stressing for video card than increasing resolution 1080p > 1440p. Am i correct with this assumption?

I am looking here https://www.game-debate.com/gpu/index.php?gid=4023&gid2=4022&compare=Nvidia%20GeForce%20RTX%202070-vs-Nvidia%20GeForce%20RTX%202080 for frames on 2070/2080 on 1080p and it looks like both can't run 90% of the games at stable 144 fps. Some it only runs at 80-100fps. Does it mean 144hz won't be of any use then?

Can someone explain me whats more taxing on performance refresh rate or resolution and what hardware to people use to game with 1440p 144hz?

1920 × 1080 × 144 = 299 million pixels per second
2560 × 1440 × 60 = 221 million pixels per second

Maintaining 144 FPS at 1080p is more GPU intensive than maintaining 60 FPS at 1440p.

Increasing the refresh rate of the monitor doesn't affect your framerate. If you are getting 100 FPS, and you change from a 1080p 60 Hz monitor to a 1080p 144 Hz monitor, you will still be getting 100 FPS afterward, thus your gaming performance is unaffected. If you change from a 1080p monitor to a 1440p monitor, your FPS will drop from 100 to ≈62. Of course, changing your gaming performance to reach 144 FPS if you weren't getting it before would require more GPU power.

Makes sense, cheers! Any good 24/27 1080 144hz monitor you can recommend?
The games i am playing are quite dynamic so i am thinking i would probably benefit from higher refresh rate more than from resolution.
