Sorry, the AIW 8500 is a single head "dual display" model just like the AIW 7500 and 8500dv. It does support hydravision...yes, so the TV-out can support a different/seperate display, for instance: watch a movie on the TV while working on your desktop instead of just the "Clone Mode" of the original Radeon, but it is not a dual head card...1 CRT OR DFP + a TV only.
