the problem is the GPU. novidio can't handle multiple displays plugged into it, especially when using features like gsync and framegen.
use the 4070ti, it's more stable, and roll back your drivers to the last ones released before the 5000 series released, it's like 566 or something.
also plug your extra monitors into your cpu (video ports on your motherboard) instead of your gpu.
go watch this video if you want a more detailed analysis.
