Question Best CPU for 2560 x 1440 144hz monitor

[gplayersv]

I don't understand the connection between CPU and resolution/refresh rate. Can someone explain how they relate?
Also, what CPU's do you think would be great choices at this moment for a monitor running a resolution of 2560 x 1440 144hz?
I'm assuming GPU is not an issue here, let's just abstract that away.
Something like this blows my mind - https://www.anandtech.com/bench/product/2274?vs=2263. I would expect the CPU matters more.

No real connection with resolution, other than that at high res, most GPUs deliver much lower frame rates, so many seem to think that a weaker CPU is somehow 'ok' at 1440P. I will simply counter that If you can't get consistent 144+ fps at 1080P, you sure as heck are not getting it at 1440P either...

1440P at 144 Hz is going to require a 2080Ti for most of the newest games...; granted, folks got by with 1080/1080Ti on games of 2-3 years ago, but, some games are more demanding graphically than others...

In short, if you want a 144 Hz monitor, I'd try hard to get a 2070 or above, and, start my searching for a CPU at the 9700K. (If only wanting high FPS for stupid CS:GO, then much lesser CPUs and GPUs will do ...)

It is true, however , that since 4k is so demanding of most GPUs that most CPUs of even an R5-1600 and above all give similar frame rates...usually much lower than frame rates achieved at 1440P.

I already have the monitor, it's this one https://www.dell.com/en-us/shop/del...dgf/apd/210-arcj/monitors-monitor-accessories
Why would I pick an i7-9700k or i9-9900k over a i5-8400? From the link in my original post I don't really see a reason. It's only ~2 fps (in those games at least) for a lot more money.
