Two different GPUs for video rendering?

[HelyXince]

Hey everyone,

 

So this is the deal: I want to buy a new GPU in a few years (curently have the 970 and I am satisfied with it). I know you can (for gaming) use one GPU as a PhysX engine and the other one for the actual graphics.

But I wanted to know, will you get any improved performance with video rendering when having two different GPUs?

 

Thanks in advance

I do not believe so, as a program like that will use one GPU I think.

 

For people who have more experience with programs like that, please correct me if I'm wrong.

Yes you can. Turn off SLI function. Go to Sony Vegas and select your second GPU as main Cuda render device. Then go to NVidia panel control and select your first GPU as the main source for media activities such as Gaming, etc. When you're gaming, you will see that there's less MB being used on the second GPU and that's because it's doing nothing. As where when you're rendering and gaming you will see different usages in both of the video cards and thats because they're processing different stuff. Then again, SLI mode puts the same usage on both video cards since both have to render the image presented on the game. You will pretty much notice what those cards are doing.

That's not exactly what the person is referring to. They're thinking about the concept of using two different video cards for video editing at the same time. Not two different tasks. I already know you can do the above in the quote. My interpretation might be incorrect though.
