physx without sli mobo?

I got a small question, is there a way to get delicated card for phyx when I only have 1 psi-e 16. Like for example , can I get like a dirt cheap 8XXX pci card series and use it as phyx card?
 
It would probably work but would be pretty slow. If you have a x1 or x4 slot that would be better than PCI. Adapters are available to convert an x16 card to either of those slots. Or the end of the slot can be removed/melted off and it will fit.
 
Not sure if this applies to physx, but you need a card that has at least 32SPs to be CUDA-capable ( with the latest drivers). Might pay to check with Keys or BFG.
 
I don't see how this can work. AFAIK, the requirement is a PCI-e 4x slot for dedicated PhysX cards. At least that is the new spec of PhysX "certified" motherboards coming out. A 4x PCI-e slot.

And as mentioned above, there is a minimum of 32 shaders and 256MB requirement for any PhysX GPU. That means, 8600GT or 9500GT minimum. I have seen PCI 9500GTs on Neweggs site, but they are like 90 bucks. Honestly, I wouldn't bother with this at all. If your current GPU isn't enough (what is that by the way?) then I would sell it, use that money and the money you "would have" been spending on a PCI 9500GT, and get yourself a beefier Nvidia GPU.

Give us your system specs please.
 
does this mean an 8500 GT wouldnt work? B/C I have been trying to get an 8500 GT to fold next to an 8800 GT with no luck so far. So my question is, will an 8500 GT be able to fold?

We were talking about PhysX. As far as CUDA capable GPU's, they are 8 series or greater. I do not believe there are any minimum GPU requirements other than that for CUDA applications such as Folding @ Home.

I am waiting for someone to come out with a GPU with CUDA support and a USB 2.0 interface.


The possibilities of building a render farm that way , sigh.
Yeah I am dreaming 🙂
 
^ What about USB 3.0? 🙂

PCI cards work from what I have read of people trying them but they run too slowly and like Keys said they are not worth the money. If you have a free x1 slot you can use a 9600GT/8800GT. A x1 slot, especially a x1 2.0, has a bunch more bandwidth than a regular PCI slot. I may be trying that with my next upgrade.

If I'm reading the available info correctly, the motherboard just needs an extra 4x or better PCIE slot. So maybe if you find a motherboard with a PCIE 16x slot and with an extra 4x (or better) it should theoretically work.
 
I have the BIOSTAR TA790GXB A2+ AM2+/AM2 AMD 790GX ATX AMD mobo, free mobo when i pick up my phenom II 940 and in case u want to know cosair 650 psu

Other than the $90 PCI 9500 GT, you might be able to shoehorn a card into the second PCIe x1 slot by breaking out the back of the slot.

Alternately sell your board and get a Biostar TA790GXE which has a second PCIe x16 (physical?) slot.
