All GeForce 8 Cards to Gain PhysX Engine Support Says NVIDIA
Video card giant NVIDIA, which completed the acquisition of AGEIA Technologies the day before, is now starting to port AGEIA's PhysX engine software to run on its GeForce 8 cards, according to The Tech Report. During a financial call, NVIDIA CEO Jen-Hseun Huang revealed that the ported engine will bring enhanced physics capabilities to all of the company's existing GeForce 8 cards.

We're working toward the physics-engine-to-CUDA port as we speak. And we intend to throw a lot of resources at it. You know, I wouldn't be surprised if it helps our GPU sales even in advance of [the port's completion]. The reason is, [it's] just gonna be a software download. Every single GPU that is CUDA-enabled will be able to run the physics engine when it comes... Every one of our GeForce 8-series GPUs runs CUDA.Huang also added that the integration shall encourage people to spend more on graphics processing hardware, and maybe start to buy two or three graphics cards, where one of them will work for physics only.

This point leads to another question - would this improve my 3Dmark06 score? Maybe all the Nividia cards will get better scores, besides people with high performing CPU's?
The way this works with a single card, is some GPU and ram power is taken for use for Physx calcuations.
In SLI or tri SLI, you can dedicated one card to JUST physx.
This wont help 3dmark or any benchies at all, unless they support physx.
see any x1k card or newer can be used as a PPU given the games engine is writen to support it, but because Havoc stoped dev on GPU Phsyix we are stuck without any wide range support for gpu as a ppu currently.
the only thing i can say is nvidia better offer pci-e 1x videocards cheap that can be used as a ppu, and if they are smart they will allow them to work along side amd/ati and intel videocards running as a pure ppu.
I guess people who have a 8x card with extra x16 slot who might buy the 9x card will keep this in the second slot and use it as PPU.
any card gf8 and up will be supported learn to read/think/comprehind.
older chips didnt support their programability system needed to run as a ppu, its also why u couldnt run folding at home on them, they just didnt have the shader power to do the job.
people do come on here tired/drunk/etc.
If they really wanted to they could have made it a speciallity of the 9x series, so that people would consider upgrading to 9x series but instead they mentioned only about 8x series. Besides in the computing world one doesn't simply assume stuff like that.
Its 8 series AND UP that supports this.
I don't see why you seem to want to keep bringing up that the added physics lowers performance. It doesn't, it lowers framerate. It drastically improves physics performance, and the lowered framerate is because the extra physics objects need to be drawn by the GPU. More things to draw=lower framerate. To call it a performance hit you would have to show me that the same physics being calculated without the dedicated physics processor(be it PPU or GPU) was higher than with a dedicated physics processor.
What you are saying is the equivalant of saying 3Dmark06 run at 1900x1200 4AA 8AF shows a performance hit over 3Dmark06 run at 1024x768 no AA or AF. No, it doesn't show a performance hit, it shows the same performance, just applied to different areas.
CPU calulating the pysics
as for havoc pysics games CPU calulates the pysics and gpu draws it on screen

this at least going by past acctions of nvidia will endup with phsyx games runnin on their cards, intel will eventuly get cards out that run havoc gpu based phsyics, and amd/ati will endup with their own version.........yet another glide type mess........( i hate glide!!!!)
