Do 8800's have a physics engine onboard?

there is no physics chip on the 8800s afaik. on the x2900 i believe there is. physics right now are run by cpu and/or dual core computers. the physx card was to expensive and only few unpopular games supported it ;so it slowly fazed out.
 
All of the 8800s have Nvidia's Quantum effects physics processing technology.
I feel bad for all the suckers who bought that piece of shit phys-x card lol.
 
It basiclly mean they physics will be done by the unified shaders. 128 Shaders on the GTX splitted between Vertex Shaders/ Pixel Shaders and Physic Opperations

That is how Nvidia plan to use a 3rd card on 680i boards to do physics while the 2 others do pixel and vertex shaders. If you dont have 3 cards then the physic and pixel and vertex will be done on the 1 or 2 card in SLI.

It's of course faster to have 3 cards with one just doing physics but not required.

Don't ask when because games have to support it and that take time to develop. So future games might take advantage of that but it will never accelerate your old games.

I think that sums it up.

$200 physx card sure sounds a lot better then a 3rd $500+ 8800gtx just to do physics.

yeah. im sure you'll be able to use a single one to do physics and play the game, but your frame rate will be like 15fps if that
 
Not sure about Nvidia but from the ATi side of things you can use last-gen cards for physics - I'll be using one of my X1900s as a "free" physics card with two new R600s

You dont need a GTX to do that... a simple 8800 GTS 320 or hell even a 8600GTS will probably beat a Phys-X...
