Multi GPU setup without SLI

[spintroniX]

I do deep learning, which maxes out my 1080Ti. This renders my system more or less unusable.

Is it possible to get a secondary card, like a GT1030 to run the display while the 1080Ti does the number crunching?

I'm thinking it should be, provided the monitor input comes from the 1030, but don't want to rush out and do something that may be obviously stupid.

Edit: running a samsung mu6300 4K display

It should work fine. The problem might occur if/when you want to play games. Generally it's going to use the card connected to the display you are using to accelerate the game you are playing. If you're just number crunching in the background usually you can choose which GPU you use.
