Question / Help Second video card in computer to record video in OBS

[777GAMES]

Hello!
I want to connect a second video card to computer and use it to record video in OBS. Now I use Asus PCI-Ex GeForce GTX 1080 Ti. I want to use Asus PCI-Ex GeForce GTX 1060 to record video. I have a question, will the encoder of the second video card be seen in OBS?

I don't know how that works but with a little bit of research i came to this youtube video : https://www.youtube.com/watch?v=Q_blwJ8kVdo
Im not familiar with recording or streaming with two video cards in obs.
So this is the best i can do.

You will gain very little if anything by installing the second nvidia card.
The NVENC encoder already exists on dedicated components of your 1080ti. Adding a 1060 just for nvenc won't help as much as you'd think, especially not if you're on a 16-lane CPU.

Yeah what Harold said

I want to use 1080 ti for gaming only. And 1060 used only for video processing in OBS. Сan these video cards work in this mode?
That's what I meant.

You don't relieve your GPU from stress if you build in a second GPU. It looks as if this were a smart move, but actually you will not see an improvement if you do. The problem is that raw frame data has to be transferred via pci-e bus from one gpu to cpu memory and from there to the other gpu where it is rendered for stream. This 2 times transfer is stressing the computer more than you gain by distributing computing power to 2 gpu's. If you render on the same gpu where you're capturing, it's just transfer within that gpu's memory, if at all - may be that only pointers are handled and not even data actually being copied.
