Stupid multi GPU&Monitor questions

[Woltox]

Heyall
Been thinking of this for a while.

Im running atm 2x monitors (1080p), where 1 monitor is for gaming and other is for socials like discord/spotify.
If I am to run each screen off different GPUs are there fps to gain from that (example using my prev generation GPU on my second monitor) ?

Anyhow thanks for the future response

not really anything to gain, id plug them all into the main gpu.

In SLI or Crossfire only card has active Display Outputs (mostly the top one)

 

if there a seperated you have to figured that out by useself PS: PhysX is not a good idee ^^
