Just a thought but has anyone got any ideas on whether ATI's new "GPU for physics" will work independently of the graphics subsystem? i.e. could I just put an X1600XT in and install the ATI physics software and have a PPU next to my nVidia graphics card? would be pretty potent marketing exercise - undercutting Ageia AND out performing them with a non-dedicated board that can be used as a graphics board too!
