This is a kinda off topic question.

My neighbor just built a new computer. The MB came with a nice video 
card but he purchased a GeForce 7900GS duel monitor support card as 
well. We are going to install XP and Ubuntu. But here is the thing: if 
you have three video ports, can you run them? More importantly, can you 
run them with Ubuntu?
