I have a Geforce GT 640 and I'm thinking of running dual monitors on my system. I have two VGA monitors, and I'm aware that I have two DVI-D's and an HDMI port on my card, which I would not buy adapters for it. Can I extend my desktop with integrated graphics enabled? And if i'm gaming, would it only display on the monitor where it's connected to my GPU? I don't mind gaming on one screen.
EDIT: My motherboard is a Gigabyte H61M-S2P
