A quality B650 motherboard can fully support both 7800X3D and likely the future 9800X3D, as AM5 specs remain similar. Choose based on your needed features, and consider PCIe 5.0 support - though it's unlikely to matter during the PC's lifespan.

For a hassle-free setup with the latest Ryzen CPUs, X870/X870E boards are your best plug-and-play options.
