I was wondering if the Radeon X1950XT will fit on a GIGABYTE GA-P35-DS3R using a COOLER MASTER Centurion 5. The reason I ask is because the X1950XT takes up 2 slots, and on the Mobo it shows the x16 slot at the top, and I don't see how the top slot on the card will fit. Please someone help me, thanks.
