Build advice 3 4k hdr monitors in surround mode

[fus10n]

So, a mate of mine wants to run 3x 4k hdr monitors in surround mode. Making it 1 big wide screen. He has a rtx 2060. I can only find benchmark tests for someone who tried a nvidia 1080 and it was able to run it, but the fps was very low. I'm assuming the 2060 wont be better.

So the question is, if he buys a 2070, 2080 or a 2080 super will these work better?
