Guys, he is looking for a card that has DUAL HEAD for 3D GAMING, not just a card with dual head (2D)...
To my knowledge dual head gaming is more dependent on the game you are playing not the video card.... a special patch would have to be made available for that specific game (FS2000 is one such game) so that the video card can enable dual head. For instance, for UT2003 to be able to support Matrox's surround gaming (3x monitors) the developers had to create a patch for the Perhelia.
