So I currently have an ROG XG35VQ 35” 3440x1440 monitor and I have my old 1080p monitor lying around somewhere. I don’t space right now to test out dual monitor and wanted to just ask in advance. If I were to have YouTube running on the second monitor while gaming on my main monitor, will the performance be hit hard?

Ryzen 7 1700 at 3.9GHz
Gigabyte AB350- gaming 3
EVGA 1080ti ftw3
Corsair vengeance rgb pro 16GB 3200mhz
500gb Samsung 860 ssd
EVGA supernova g3 1000w gold+

It won't hurt performance at all, stuff like web/YT/Netflix has very minimal usage. Now if you were running a second game client on that screen then that's a whole different story.
