Or would it need to have 1gpu for every 2 screens, meaning a 2gpu setup? Subsequently, would I also need to be running them on like a threadripper motherboard to avoid pcie down scaling each gpu to x8 each instead of x16?

All hypothetical so i apologive for not being able to provide actual specs. Im helping someone setup a mid-tier racing sim with 1 monitor so providing the actual specs Im using would be obsolete. We were just speculating what it would take to build a god-tier racing sim.

Also, I apologize if this isnt the correct community for this post. I didnt find anything when I tried searching different iterations of ‘AskTechSupport.’
