ATI does have dualhead cards, of course... I should have stated "more than 2 monitors".. more like, "mulit-card"
is that the card with 4 dvi inputs? are you planning too play games too. if you gamer i reccomend the 4870. and get a cheaper dvi ati graphics card. if you don't game there are cheaper solutions for ati multi monitor. i run two 8600gt xxx. no problems in vista. the only problems occur when you have two different drivers for you video cards. You also cannot mix video cards ex. amd and nvidia.
