it is no issue to combine graphic cards but im pretty sure that chrome/discord go through the main graphic card aka gpu 1, theres no compilation with drivers really too since its amd and nvidia, theres a chance if u have a monitor connected to the 1030gt that stuff u run on there will go through the 1030gt ( dual monitor setup ), i wouldnt worry about outputting on the same gpu as gaming card though, i have a 2080ti outputting 4k 120hz and 1080p 144hz at the same time without issues or fps loss, and im using a displayport to hdmi 2.1 adapter, short said i would just run with 1gpu unless u have specific bugs with a 2nd monitor then the 1030gt can help with 2nd monitor
