Yeah, I think I will be going that direction. Luckily, this isn't an urgent need, so I have the flexability to wait. It's all upgrades, so I can wait until parts are in hand, even if it takes me into 2022. Psychological security is big to me... haha.I really like the Strix boards, I would get the ASUS Strix Z690-F. I think you'll benefit from the psychological security of having DDR5, though it might make sense to wait until you've secured the RAM kit.
Thank you for all your help.
