Although I agree that PCIe Gen 4 will be a big deal in the future, I think that'd be far after the end of the AM4 socket and start of Zen 4 and DDR5, so a motherboard upgrade would probably happen by then anyways. B450 is still a pretty good choice for now unless they're planning to not upgrade their PC in the future at all (and I think they willl will, this is a midrange build it seems).Don't get B450 you will miss out on PCIE 4.0. It might not seem a big deal now but will be in the near future.
Most of the advantage of PCIe Gen 4 come from SSDs that use the PCIe layout at the moment, though.
