NVIDIA Removes Restriction on ATI GPUs with NVIDIA GPUs Processing PhysX

Good news - a step in the right direction. As an idea I've been toying with, does anyone have any idea on what specification card you can use as a dedicated physx card btw?

e.g. are either of these ok?

General rule is that more cores, the better. I have a 9800GTX+ running at 800/2000 and it tears through physx.

Anything 8 series and up will work, but either of the cards you linked would be great. I think EVGA put up some benchmarks to show the benefits of adding a 240 alongside a GTX480 for PhysX so you might want to look around on their site. It was a pretty decent boost if i recall.

Yeah I was quite surprised how much of a hit the gtx480 takes doing physx. In the gtx480 owners thread my overlclocked 5850 with my 9800gtx+ could match a gtx480 in batman with everything on max but with physx off, it get totally whooped by the gtx480.

So much for Nvidia always claiming you didn;t need a dedicated card. :rolleyes:
 
Is there any guarantee they won't be switching off phsyx support i.e. to guarantee they're not getting profit from people buying PhysX, then those who have gotten used to it don't want to have wasted their low-tier PhysX card and so buy Fermi?

not going to buy anything from nvida until they guarantee continued support.
 
its because they are bringing out a new rebadged 8800gt/9800gt/GT250 called a GT450 same card due to the surplus stock they still have.

;)

Thing is you just keep using the driver which works that doesn't have the restrictions.
 
I'm sure this move has nothing to do with the fact that Manju Hegde (CUDA/PhysX developer and former CEO of Ageia) has left nVidia to join ATi.
 
Adding an nv card for physx would drop my 2nd and 3rd pci-e 16x slots to 8x electrical slots. Would this have an impact on crossfire or does it not use enough bandwidth? Setup as below.

You can pick up a GT240 or g92 variant for £50< these days. Might be worth it for metro, mafia 2, just cause 2, etc.

i've got a spare 9500gt knocking around, is it even worth trying?

or is it more like 9800gt or above cards?

Worth a try i reckon, anything G92 based and above is what's generally regarded as the best option, but a 9500 should be able to handle some games at least i would i have thought. Just depends how heavy the PhysX is in a particular title.
 
Can I add a 3rd card to my UD5? I read somewhere that the 3rd PCI-E slot is running from a different chip or something? And the 3rd is limited to x4.
How much would I benefit from adding a GTX240 to my current rig?
