1 PC, 2 Video Cards

Not sure if this would work, just curious on thoughts. I run 3 displays on 1 Radeon R9 380, would it be possible to add another radeon card and run 2 displays off of it and keep my main display on the R9. The thought would be to run a game utilizing my R9 with no other real load and still run the other two without hurting its power.

Although this would work you would see virtually no performance increase by doing so.

You can if it's the same chip family (eg same driver) but there is no net benefit since the rendering for any application will still be on the primary GPU.
