Dedicated NVIDIA card for PhysX?

[dannyaa]

I have both an 8800gt and a GTX 260. If I put both of these into an SLI motherboard, but didn't run them in SLI mode or connect them, what I be able to use the 8800gt for PhysX and the GTX 260 for graphics?

I also have a spare 7800gt. But I don't think that card supports PhysX, does it?

You should be able to do that with the latest drivers.

the 7800GT won't support it. in order to use a card for Physx processing, it has to be at least a geforce 8 series. but technically you could buy an 8500GT and use it for physx if you wanted to.

you wont get much of a boost. in my case my 9600gso i used for physics actually bottlenecked my 2 gtx260 in sli in ut3. nvidia needs to polish physx drivers.

Hmm, interesting. Can I still run PhysX with just a single GTX 260? Will it still run well?

 

[invisik]

ya it should run fine. give the 8800gt a shot and see if it improves your fps. in my case 1 gtx260 rendered while the other did physics so no need for a 3rd in my case. you could benefit because you only have 1 gtx260, just experiment.

Sorry for the stupid question, but I'm stupido...

do I need SLI mobo to run 1 gpu for graphics and the other for physix?
I guess I do need SLI, but it never hurts to ask...

Actually, Sli + discrete physics still isn't supported by driver. You have the physx option, but doesn't let you choose which gpu to run it on, as in single card plus another for physx. In other words, the "bottlenecking" is actually due to the PC trying to run physx off your gtx260.

Single card plus another for physx will always work.

yes i believe it is supported. im able to go on the control panel enable sli and it gives me the option to dedicate 9600gso for physx.

How come it didn't work on my 9800gx2? I suck...

 

[Stupido]

First of all, except UT3 are any other games that support PhysiX?

Currently I'm using one GTX280 but also have 8800 GTS 512 laying around...
So I was wondering if it is good idea to go with i920/X58 mobo and later just add extra GTX280 in SLI to keep up? Or simply swap 8800 GTS with 280 and buy the "the-big-of-today" card?

Yeah, it's a small list, but there are some, even big titles like GRAW/GRAW2 and AoE3:WarChiefs, but the list is small, but growing (how fast has yet to be seen).

The list isn't as long as all the PhysX titles because there's no division between CPU and GPU physics in most lists, and they are not the same just like Havok based games =/= Havok GPU physics. That's also part of the problem with talking about future titles because many people talk about a game having PhysX and then it turns out to be CPU only.
