Whats the best hardware to use for the emby server if I want it to work to its best potential?

That is a totally loaded question. Are you talking unlimited budget, unlimited power, power limits, what? Are you staying within the regular license terms and not going to the max? 

For transcoding, any 12th gen i5 class or higher processor will be able to handle the maximum number of users under a normal license if each and every one of them is doing a 4k transcode while using quicksync. The bootleneck becomes your storage and potentially your network if you're using a separate machine as your server than your storage.

You would be better served to read a few of the threads in this particular group to get an idea of what is "best", as it all comes down to your usage scenario. Ideally if you want us hardware people to answer you, we need more information, please.
