NVIDIA Removes Restriction on ATI GPUs with NVIDIA GPUs Processing PhysX
NVIDIA has reportedly removed the driver-level code which restricts users from having an NVIDIA GeForce GPU process PhysX with an ATI Radeon GPU in the lead, processing graphics. Version 257.15 Beta of the GeForce drivers brought about this change. Possible commercial interests may have played NVIDIA's previous decision to prevent the use of GeForce GPUs to process PhysX with ATI Radeon GPUs, where users could buy an inexpensive GeForce GPU to go with a high-end DirectX 11 compliant Radeon GPU, thereby reducing NVIDIA's margins, though officially NVIDIA maintained that the restriction was in place to ensure Quality Assurance. The present move also seems to have commercial interests in mind, as NVIDIA could clear inventories of GeForce GPUs at least to users of ATI Radeon GPUs. NVIDIA replenished its high-end offering recently with the DirectX 11 compliant GeForce 400 series GPUs.
Update (28/05): A fresh report by Anandtech says that the ability to use GeForce for PhysX in systems with graphics led by Radeon GPUs with the 257.15 beta driver is just a bug and not a feature. It means that this ability is one-off for this particular version of the driver, and future drivers may not feature it.

If what you mean by enough is it will not limit framerate when paired with a 5870 then no. I have seen people benchmark Batman: AA and they have reported that the 8800gt 512mb vanilla had less frames operating as dedicated physX than when using 8800gts 512mb and even moreso than a GTX 260 when being used with a 5870. That means frames are limited by the card when running at max resolutions and settings. Now with lesser systems it may not be the case though. I am assuming highend since this is a gaming forum and I didn't explain it fully. ;)

a 9600gso and 9800gt both come out equal in physx performance
I cant believe you need a powerful card to run physx, not powerful maybe mid range these days but those cards arnt cheapo its definitely not worth it at all. Sure you can choose to do that if you like but it doesn't mean its value for money.
Never got why not allow as it means more sales that wouldn't have happened.
I don't have a HD5850, but I do have an GTX470, I'll test the 9600GT vs. GTX285 to see if there is a difference in performance between thet two this weekend.Damn, that really sucks.

Sounded too good to be true, didn't it? No wonder no official announcement.
You all know who you are. :)
I'm sure someone has a copy somewhere if I ever want to try it.
and ppl who consider buying nv card for phisyx would be pissed right now.
EDIT : and btw btanur should update the news
