So I have a R5 1600X, and a display and GPU for gaming.
I had the idea of buying a crappy GPU and monitor just to have on the side so I could watch Youtube or work on a doc while gaming. My idea is to buy a something like a GT710 and a 60hz 21-inch monitor, plug the GT710 into the monitor and have the extra unused cores while gaming go to the second monitor.

I feel like there's something wrong with this idea though, so If anybody had done this before, please let me know how it works out.
 

GTX 1060 6gb, I was worried that it might effect FPS and overall performance, but it seems like it may not pose an issue after some thought haha!
