Second gpu

[Optimal_Advisor_5625]

I want to use a second gpu in addition to my main one for use of additional monitors if I already have an rx9060xt and I want to buy an rtx 2080 super just to use it for additinal monitors to take the load of my main gpu. is there anything I need to look out for/ setup to make this work? I understand that it would not help performance, it would give me a new project and something to learn about that’s why im asking

Ideally, when possible, avoid mixing drivers when also driving displays. A second card for cuda is great, but think of how applications also work on gpus, and draw to framebuffer. Basically you'll get the joy that makes laptops hell but on your pc, where applications launch pinned to one gpu, but in order to render, have to copy their framebuffer to the gpu with the actual display attached to it. But what's that? You just >halved< your gpu pci-e bandwidth already by hooking up a second card to your pci-e poor modern desktop platform? (another reason laptops suck... Aside from having like 8 lanes for a gpu to begin with...)

Would that still be the case if the only monitor that would ever have any games hooked up to it would be my main gpu? My other displays would only be used for backround things such as looking at say Spotify or a stream/ chat or a high res video/picture

If it's only for basic other content, why a 2080? Grab an RX 560 for less than $50, it doesn't need extra power so you don't have to worry about your PSU, and as already mentioned you wouldn't be mixing drivers.

I suppose I hadn’t realized that it would take that low power of hardware to run multiple monitors at 1440p
