Triple screen choice

Hi everyone, I'm currently in VR (G2) questioning myself on switching to triples.

Immersion is great in VR, but there is a lack of side perception and a pimax would be too expensive. So I'm checking for triples and... I'm f'in lost! There is too much info! If I wanted to get there, what would you advise for in screen size and resolution, without spending thousands?

I have a 3080ti FE, R7 5800X and 32GO ram.

Thanks!
