Building fastest video editing system possible with GTX 670 and 580s - configuration question

WellingtonFilms · Mar 7, 2016

Hi, I am new here, but I would welcome your advice.

I have inherited 2 x GTX 580 3072MB, 2 x GTX 580 1536MB and one GTX 670. I am trying to configure the most powerful editing system using these admittedly old cards. I use Premiere Pro CC and have a GA-X79-UP4 mobo, which has 4 PCIe slots (two x8 and two x16).

I am wondering if I can use the two better 580s in SLI configuration in the x16 slots and then the 670 in the x8 slot to add rendering power? Is it best to use the 670 for PhysX?

Or is it better to use them all separately in a non-SLI configuration?

I need to keep one slot free for another card (Decklink 4K Extreme).

Many thanks.

Yeah putting the two 580s with 3GB of VRAM in SLI would be a good idea, although I'm not sure to what extent you could utilize other GPUs in the system. Having a separate PhysX card is entirely redundant at that point of performance as the onboard PhysX processing of the SLI 580s will far outpace anything the 670 can do on its own.

Thank so much for the speedy answer.

I figured the SLI option was the best out of what I have. Is there no use though for what is singly the best GPU that I have (the 670)? What about dedicated CUDA or OpenGL? I must admit, I don't fully understand this yet, so all help is greatfully received.

Would adding the 670 slow down the 580 SLI pair?

SLI 3gb 580s would be the way to go.

Most current cpus only have 16x pci-e lanes anyway, so running two at 8x would be the the way to go. If you added another card, you would break your SLI config as SLI requires 8x for each gpu (unless you have a socket 2011 system or a motherboard with a PLX switch).

TLDR:
2x 3gb 580 in SLI.

No, adding the 670 would not slow down the 580 pair. If you can utilize it go ahead and put it in the system as well. Just keep in mind that for 580 SLI + 670 you'll need somewhere along the lines of a 1000W PSU.

edit: my bad, he is using a 2011 system, so ignore my 16lane warning.

Sell all the old cards, buy two newer ones.

Thanks very much for that. I tried the two 580s in the 16x slots in dual SLI and it worked fine. I then added another 580 in the 8x slot, still with the first two connected with the dual SLI connector but Nvidea no longer recognised the first two as being SLI. Is that normal?

Is there no way to add a third card as non-SLI, whilst keeping the first pair as SLI? Thanks again.
