Two GPUs, SLI Cable Needed??

hi
i wanted to know if i had a gtx 660 and a 670 and wanted to use the first one for physx and the second one for rendering, do i need to use an SLI cable or not??

No cable is needed unless you are using SLI, which you aren't.

For Physx, no you don't need a SLI cable for both GPUs. Even if you want to SLI both cards, you can't SLI them anyway.

Can I Use Two GPUs for physx ?

You use one as dedicated physx

 

[cuecuemore]

You can run two identical GPUs in SLI and render and compute PhysX on both of them, just an FYI.

But you don't really gain all that much with a dedicated physx card, especially with a gtx 670...

a gtx 660 for phsx a 96 cuda core gt430 more than enough for dedicated physx yes it will just give 2-3 fps more on a gtx 670 maybe less
