PhysX cards are on the way out right now, mark my words.
And the 8800s have physics support, granted a seperate card would take some stress off the rest of the system, no doubt. But with current prices of PhysX cards from Ageia being around $135 and the performance increases being somewhat negligible in rigs similar to mine I really don't see the point in it.
Actually my rig is set up with a nice PSU and my motherboard is SLI ready so my next upgrade will probably be another 8800 GTS when they become available at sub $200 prices.
