I have a gateway MD2614u laptop. The video card is a ATI radeon hd 3200. running vista 64 bit. When i go to the ati website to update my video driver I have a choice of notebook and the closest card to mine is mobility radeon hd 3200. If i choose integrated motherboard graphics my choice is radeon 3200 series. Which one is the right one? Does the hd part mean anything?
