If only your CPU becomes a limiting factor at one point you can simply upgrade your CPU to a few generations newer cpu without having to swap out your motherboard. You can’t really do that with Intel (AFAIK they switch platforms every 2 CPU generations so depending on your CPU you may not be table to upgrade at all (can happen with AMD too, but not that frequent)
