Stacking Clients to increase performance?

I'm playing Path of Exile, and I have all my settings as low as I can on each client. The game runs smooth at 20 FPS until I get into heavy combat with 6 sporkers blasting away. I have it configures so that I can see all 6 game clients on my screen at once. Would it be less taxing on my computer if I stacked all the clients underneath each other so that the computer only actually had to display one screen at a time?

Nope

The game and your PC will still be doing everything it was doing, you just won't see the window
