What happened was that Nvidia bought AGEIA and while looking under the hood of physx they found that with several "firmware mods" 8800 may be able to run physx card like physics inside the 8800 series cards

Quote:

Good news for folks with a GeForce 8 GPU and lots of questions about how the recent Ageia acquisition would affect them: your current card will be receiving PhysX support. When NVIDIA CEO Jen-Hsun Huang was questioned in a recent conference call, he noted that the firm was currently “working towards the physics-engine-to-CUDA port,” and it could be delivered as “a software update” to every card that’s CUDA-enabled (read: all of the GeForce 8 GPUs). Sadly, the bigwig still wouldn’t say when to expect the release of the first PhysX port, but we really can’t imagine it taking too awfully long now

Why post old news? nVidia has already stated that they currently porting the Physx API to run on CUDA. So it's only a matter of months before the DX10 cards from nVidia can do it.

When that happens I might just buy a 9600GT to run it or maybe get a GT200 and use one of these GTXs as a physics card.

Considering they won't be rendering together I presume you don't need identical cards nor do you need a SLI link? If so that'll put my second PCI-e slot to use, not sure what I'll do with the 8x one though. That is actually the one for physics cards.

i looked if anyone has posted here about this and nobody has.
apart from you two everyone is oblivious to anything tech...

ya know the beauty of 8800 shaders is that they can do vertex and pixel processing at the same time. maybe just maybe some of those shaders can be reprogrammed to be used for physics.

dunno just thinking around some boxes ;)

They can't do both pixel and vertex at the same time. Only one at a time. But there is 128 of them that can change dynamically to the needs of either pixel or vertex.

That is in fact how all DX10 cards works. AMD/ATI is slightly different and groups them into 64 clusters but they are dynamically assigned.

Also if you bother to read up on stream processing then you'll understand that these shaders can be programed to do what ever you want them to do.

In fact ATI x1k series cards has the ability to be reprogrammed to support what ever you want on them. They were originally going to support physics and they also support Folding@Home on it.

With the 8k series nVidia released CUDA which is a C based programming language that allows anyone to program code to run on the GPUs.

So if you want a physics engine to run on a card then it's just a matter of converting the code from what ever language to the CUDA one.

do you know anything about pico computing ?
im assuming that - the 8800 gpus can be used the same way.
hopefully it becomes more opened up so somebody writes a program to generate rainbow tables on your 8800gtx

I just randomly thought of the coolest geek scenario..

With using some of the pro-sumer rated cards and beign able to write the software that it uses on them for the drivers.. It woudl be so darn kick arse if you could run an SLI style setup, but one of the cards be dedicated to running an ultra high graphics resolution OS comparible to the new Mac OS, and sort of a hybrid between MacOS and Vista... except make it all crazy intense.. be every geeks fan come true ;)

ermm - wtf are you talking about ?

The physx drivers are out now.
