2 different gpus on the same system

[DuckHunterZx]

So I am looking to get a new pc with a ryzen 7 3700x and an msi x470 gaming pro carbon. I haven't totally decided on the GPU, but i'm leaning towards an rx 5700. My old PC has a r7 370 gpu, which is way too powerful for my parents needs. I recently came across an app that could benefit from 2 graphics cards (PFTrack). Also there's a lot of gameplay recording on my PC, so I'd appreciate if I can record with one card, play with the other. Note that I'm not talking about a SLI/Crossfire configuration, talking about having them do their own thing. Do you know of any more workflows that take advantage of such a set up? Also how can I set it up?

 

Another concern of mine is PCI lanes, this is why i listed the cpu, mobo and chipset. I am worried that 2 GPUs, 2 M.2 drives and a sound card would be too much for my mobo and cpu to handle. I don't think my second gpu saturates a pcie 3.0 x8 interface although i am not sure at all, so I am willing to make that sacrifice... Thank you to all who reply.

You won’t be recording from a certain card as they both would have to render the image. Which isn’t being done.

 

Best to check the mobo manual for lane usage. Either way that old card can’t saturate a 3.0 lane at 8x.

So if I wish to use Relive to record, the rendering card takes the load? What If i use something like OBS then set it to encode using the second card? Thanks

If you can properly select a specific encoder it could work but using an older one would lessen the quality of that what you want. 

 

Not something I’d recommend.

 Alright, you definitely can do it on obs, but i fail to see why the quality would be reduced. Now my question is can I do the same using Relive instead of OBS, as the former has been far more convenient for me. Thanks

The encoder decides the quality. That’s why. 

 

Never used that program. I use obs or my elgato software.

Well the quality has not been bad so far, I just go on relive and decide the recording settings (bitrate, etc), I doubt this would change using a newer GPU. Is the encoder that different to the point there's noticeable difference despite using the same settings? Both cards use VCE as far as I know. Thanks
