what is hardest to drive for a gpu 3440x1440 100hz or 3840 x 2160 60hz?

Solution
Bit of quick maths shows they're virtually identical.

(3440x1440 ) x 100 = 495360000
(3840x2160) x 60 = 497664000

To run 100htz & consistently hit 100fps however relies on having a cpu that's capable as well as the gpu.

60htz (60fps) not so much.

They are identical in bandwidth (pixels/sec) requirements - 5Gbps. Hence the computing requirements in a game (to create those pixels) are similar.
However the 100Hz is not typical used for games, more for video in some countries (that still have analog television in this millennium, but that's another story). Note that the video is "displayed" using a different hardware inside the video card.

4k is more or less the same with all cpus

I have two 1920x1080, 24", monitors, side-by-side. That's 3840x1080, plenty space for multiple windows, and cheaper than what you want to do.

Well... to each it's own.
The 28" 4k monitors don't have enough real screen surface for me, the items are displayed way too small for my eyes.
And 1080 is "tall enough", more than that will make my head tilt up/down to cover the whole screen.

I learn a while back that straining my eyes is never a good thing, eyesight once gone, doesn't come back. But that's just my personal lesson learned.
