Exclamation What is the best dedicated PhysX card?

Hi i have a ZOTZC GEFORCE GTX480 and i wanna add a dedicated PhysX card to render physx what is the best card to do this? if u say GT 240 i say the GT240 designed base DX10.1 and the GTX480 designed base DX11 & if u say GTS 250 i say he is designed on DX10 and the GTX480 designed base DX11.did the physx card related with the DX. i mean if i use a GTX480 for graphics + GT240 for physx with game use the DX11 like Battlefield Bad Company 2 the game graphics work in DX11 and physx work in DX10.1 or the physx already non related with the DX11 or DX10 or DX9c.....etc.or if the game run in DX11 the graphics card must be supported the DX11 to run the GAME IN DX11 & the PHYSX card must be supported the DX11 to run the game in DX11 mode i mean ((( graphics & PHYSX ))).
Thank you.

I have a Sparkle Low-Profile GTS 250 1Gb and it seems to handle Physx extremely well. I have a feeling that a GT240 wouldn't be fast enough to process physx better than a 480 could.

If I were you, I'd get at least a 9800GT... preferably a GTS 250. People will tell you that you don't need that much power, but you certainly will in some cases if you want to maintain good performance, and what's the point of buying a Physx card at all if you still have a Physx related bottleneck at some point? Get the best thing you can afford that isn't a total waste of power.

PhysX doesn't use DirectX for anything, it is calculated using Cuda.
You can be sure that 4xx series is best in terms of performance due to the better arcitechture for computing.

I'm sure the 480 is the fastest card for processing Physx, but when you want to move the Physx load to another card, you want something that won't be a total waste, so obviously you aren't going to run a second 480 for dedicated Physx. That's why I mentioned the GTS 250.

Hopefully nvidia will release a "perfect" dedicated Physx card using the Fermi architecture before too long. Maybe 128SPs, and high clock speeds in all the right areas, low(ish) power requirements and extremely low idle temps and power consumption.

I'm surprised they haven't yet. They did just unban ati from using physx and got rid of timebomb in 257 drivers so maybe now they'll release a card that both users will buy and spread physics to a mainstream level.

From the sounds of it, the unban wasn't intentional but they were *shocked* over the positive response. Wow no kidding??

Hmmm.

/looks @ HD 5830 + GTX 465...

Hmmm.

Heh, I'd never use a 465 for Physx. It uses just as much power as the 470.

The 470 is a very solid card, especially when overclocked, but its severely lacking in the areas that I consider valuable for a Physx card... such as, low power consumption, low noise, low heat output, and small size.

Right on. I'm still learning about the makings of a good PhysX card.

Benchmarks from evga claim the GT 240 doesn't even hold back a GTX 480... could just be marketing. It seems like the GT 240 should be robust enough for physx at this point. But maybe a little shaky for the future. I bought a GT 240 and plan to check its physx performance. If it's not too great I want to use it in another machine anyway.

Silly question- with my 470, IN Batman AA physx is set to normal with no dedicated card and it's perfectly playable with all else maxed at 1680x1050.

Is the physx performance in this title indicative of what to expect in other titles that utilize physx? Would I really need a physx card?

If it does make that much difference, I may have to grab one.
