Two GPU Cards One PC??

[Jay Simlian]

Hey Everyone

Quick boomer question. I upgraded my nvidia 1050 ti to a Galax GTX1660 and was wondering if I can put both cards in and if there are any major benefits in doing so? I stream too and thought it might help with multiple monitors etc?
I know you need a bridge cable between the two apparently. My PSU only runs 550W and my motherboard has the extra pci slot but is a Biostar X370 GT7.

I was hoping for better framerates and less strain while streaming as I am using NVENC Encoding. (My CPU, Even though multithreaded cant seem to keep up)

SO short question is just if you think it is worth the effort or not?

Thanksss!!!

No, has to be the identical cards

 

[Jay Simlian]

thanks for the response, didn't realize they need to be exactly the same. Probably a obvious miss, haha

Not true, that's SLI not MDA.

You can run them both as MDA, but only for some DX12 titles that support it, only one that comes to mind right now is BF5.

The issue is that it often messes up your min frame rate, so not really worth it, and a 1060 should be more than good enough for most 1080p on high so no real need.

Lol, so basically they have to be identical cards.

No, that's SLI, and besides the RTX 3090, there isn't really SLI support anymore (Nvidia is dropping SLI support from pre RTX 3000 series cards from the 1st of Jan 2021, only card that doesn't match that is the 3090).

Issue is MDA support is quite rare, you'd need to test on a per title basis, must be a DX12 title. For <4k, doesn't really make sense and will near always be better to sell both cards and go one tier up if you can.

Meh, Nvidia sounds like too much effort, glad I'm in the AMD camp.

That would be the same for them, last crossfire cards were the Vega 64 cards.
Multi gpu hasn't really been a thing for awhile, it didn't really work so it's been slowly faded out.

Lol, true, didn't thought this through. I actually just meant, as a whole....jokingly. But I didn't do, nor will I do crossfire or SLI or.... Always ever just needed one card.

Summation, stick to a single GPU and make it the most powerful one you can afford...

 

[cguy]

It may be useful if you want to do two entirely different things simultaneously (e.g., encoding video or running folding@home while playing a game). Otherwise, as stated, you need apps/games with explicit multi display adaptor support.

Nvidia briefly experimented with “heterogeneous SLI” support some 7 years ago, but the benefits were marginal, and the increased complexity didn’t justify the gains.

There is also gpu passthrough if you wanna play with that, apparently with a few hacks you can do it with consumer gpu's too now. Havent tried it myself yet.
