You could try Ctrl+Alt+F* to get another session/terminal. Or if you use Steam, use the Steam overlay browser. Could also try another Window and/or display manager. At home I have set up multi seat, meaning multiple graphics (GFX)/sound cards, separate screen keyboard and mouse, connected to the same PC. The only problem is that one of the GFX cards goes to sleep when inactive for a few hours, so I have to restart the display manager to wake it up, but the performance is excellent, we play games simultaneously, watch Youtube or what not - without any performance issues, on a several years old PC.
