ATI’s physics will have support for Havok FX as well as asymmetrical configurations meaning gamers can delivery physics in a 1+1 and a 2 +1 Crossfire configuration.

Also ATI says they are going to be simply faster than an Ageia PhysX card even with using a X1600 XT and that a X1900 XT should deliver 9 X the performance of an Ageia PhysX card.
