Main consideration for me right now is the fact that while hopping onboard AM5 is costlier than, say, moving from a 3900X to a 5800x3D, with the AM5 motherboard you are in good shape for Zen 5 and maybe even Zen 6 a year or two down the line. Presumably, at that time you would recoup the extra expense for going AM5/DDR5 early, because you'd have to do it anyway to move from Zen2/3 to Zen 5. So I really think it boils down to whatever my disposable funds are limited to when moving up. I think I may end up with the 5800X3d and transferring my 3900X (sweet cpu!) to my wife, and seeing what Zen 5 is going to bring to the party before biting the AM5 bullet.
