AMD is great for gaming on Linux, especially with projects like radv and ACO.

I'm not super interested in Linux gaming, I just want my desktop to be usable.

Honest question: If you're not interested in gaming, why even get a discrete GPU and not an integrated one? Are you interested in using it for other purposes?

I dual boot Windows for gaming. I work and code on Linux, except my monitor setup + nvidia graphics card results in a virtually unusable desktop. Integrated graphics can't run multiple 4k screens very well, if at all.

I do all my gaming on Linux and AMD works very well for it.

I'm not the author of the previous comments but I use Linux, not interested in gaming, and I have a dedicated GPU (2080ti). Mostly for working with Blender and Houdini, where the integrated one would work as well as using the CPU, at least for the workloads I'm dealing with, so having a dedicated GPU for both simulations and rendering helps a lot to speed up the workflows.

I can answer this question from my own perspective, at least. CPUs with integrated graphics are not as fast as standalone historically. Compare say, a ryzen 3600 to a 3400G.
