a family member asked if i could hook him up with card that can do dual display. He has a dell and i think his mobo is agp. Im not sure if he wants a dual display with two seperate screens or if he wants to blend the two. I was thinking of a 6600GT agp. Will that work? he wont be doing anything more than video poker, web browsing and occasionally some flash games from nickelodeon.com that his kids play.
