I’ve been kicking around the idea of getting one to mess around with, but not sure if it’s worth the price compared the the devs. using it in future titles. Looks pretty dang cool though
Seperate GPU (PPU) to handle realistic physics (water/air/cloth/solids). Here is a demo of it from a game called cellfactor. It reminds me of when you needed a seperate math co-processor to run cad programs, or when 3D-fx just hit the market (why would I want a seperate card for games? lol)

I guess nvidia is working with havok to mimic the same thing using their SLi setups (one GPU for graphics and one for physics)
