The graphics do seem to be the built-in chip, being an Intel 965GM.
I am currently running dual, but want to use four screens (on a laptop, and i will probably be criticized for that)
1 VGA and 1 HDMI and the built-in screen
Im hoping that i could get a HDMI to VGA adapter (they are pin-compatible, as i hear) and then get one of those USB external video cards (that is, if both VGA and HDMI ports will work simultaneously)
i have four built-in usb, that i am sure are spread out on two headers on the motherboard, then the standard networking, firewire, and thats about it.
I have both VGA and DVI inputs on my monitors, but not HDMI directly.
I plan to run four screens on final setup.
