The PPU add in card does very well indeed & out does the NV260-216.

I think I'd like to actually be able to play a PC demo of the game, I wasn't that keen on the demo on the 360, but there doesn't seem to be one to be had for the PC. How irritating, I wanna see the pretty physx stuff on my 8800 GTS 320 (albeit in the range of seconds per frame...). 
But yeah, we all know games that use gratuitous amounts of shiny PhysX effects run terribly on a CPU and very well on Nvidia's own hardware, that's hardly a surprise. Now if they made it run well on hardware they didn't develop themselves, that'd be an achievement.

an interesting read, cheers for the link 
makes me tempted to boot up win7 and chuck a 8800/9600 to run physx alongside my 4870..
The benchmark results for a 4870 with cpu physx are rather dire, especially when you consider that other games with similar physics effects have nowhere near the processing requirements.

ATM but they should have tested the the faster NV cards as well, and is understandable as the GPU is rendering the gfx as well & shows that there is no spare power on the GPUs for physx or they wouldn't of taken such a hit.

Those numbers don't match the other physx tests done with mirrors edge - which showed the 260-216 doing GPU physics almost 40% faster than the 9800GTX+ doing GPU physics at very similiar settings to what they are testing. It also showed the 260-216 + GPU physics against 260-216 w/ PPU to only be slightly slower - nothing like the margin they have here.
Personally I think they've screwed something up in testing as other physx tests as well as other of mirrors edge have shown that the 260 + 9600GT is roughly similiar to 260 + PPU in their tests the 260 + 9600 is showing quite a bigger performance margin.

It beats using one card to do graphics AND physics, it must do, otherwise the add in card is useless.
Using two graphics cards, one for graphics and one for physx, THAT is what is fast and it completely destroys the PCI physics setup.
Just bought a cheapo 8500GT in MM for kicks
Not the most powerful card in the world, but I'm sure it'll do just for physx
Not really that useful imo - anything from an 9800 upwards would be faster doing rendering+physics... however those 8500GT overclock quite a LOT* which might make it marginally useful - especially if you have XP or win7 and an ATI card for rendering.
* IIRC the default core is 450MHz - most will do 729MHz overclock atleast depending where the shader craps out - if your lucky and got one that does almost 1600MHz shader clock you can get almost 100% performance boost. Tho it helps if it has decent cooling i.e. the one I tested: http://aten-hosted.com/images/DSC00264S.jpg and my world record breaking 8500GT SLI setup
http://aten-hosted.com/images/DSC00378S.jpg shame it got beaten eventually by someone using cherry picked cards with faster memory than those available for sale.

rofl.. I wouldn't use an 8500GT on it's *own*, for both rendering and physx
As stated earlier, I have a 4870 already.. Once I have the 8500, I'll boot into Windows 7 and have a gander at getting the 8500gt to do the physx
*edit*
Cheers for the info on their overclockability tho, I never knew that.. fingers crossed, eh?

Not really i used a 8600GTS and found it wasnt that good

I mean that say 9800+8500 v the 9800 doing both then the 9800 would be faster in both cases... I wan't saying 8500GT for rendering and physics. I'm not sure about the 8800GT but the 9600GT would be the slowest card to see a boost from using an 8500GT for physics while it did rendering.

Im not sure if you can use a nvidia card for physx if your main card is an ATI card, having both drivers installed may be a headache
Its _supposed_ to be possible and easy in windows 7 but I've not tested that yet and is possible in XP but it can be a bit of hassle. Vista however its pretty much impossible (unless you can write your own device drivers and stuff
).
