For longtevity, I would suggest an X870 board for future CPU release options, 9800x3D for gaming, and 32GB RAM. If you ever decide to go up to a 16 core CPU you should take out the 32GB for 64GB. Don’t add an additional 32GB, there’s a difference in performance between 4 8GB and 2 32GB.
The GPU is whatever you want because it only takes 10 minutes to replace with a new one.
Have you tried booting into the operating system, or have you installed the OS yet?
