    OK, so PCI3. But if you consider this is the very budget end of the spectrum, it's not going to be used with a high-end GPU. And yes, future upgradeability is limited by the bus bandwidth.
    I don't know what most people do, but most of my PC's I run to the ground and barely ever upgrade. Just sell the old and build a new one. Much more fun.

    With those vrms I wouldn't even trust it with an athlon

    They'll be fine with anything 5600G and below (as OP mentioned), especially if paired with an air cooler so the VRM's at least get some air over them.
    I just wouldn't go enabling PBO or try to do any overclocking (unless you undervolt a little and use curve optimiser). (edited)

    Indeed. Gigabyte's 4xx series of AM4 boards were ... iffy. Hard to recommend. Wasn't really until the 5xx AM4 boards they really improved. But if you are using a down-draft cooler - e.g. Wraith series - that might help keep those very pokey VRMs cool. (edited)

    Unfortunately motherboards without PCIE 4.0 are becoming a hard sell these days.

    If it's a machine that's never going to be used for gaming in the future then sure it'll be fine but with both Nvidia and AMD releasing lower end cards with only x8 PCIE lanes and terrible memory busses it's killing off PCI 3.0.

    You can quite easily find a x16 card that performs better than a more recent x8 card at a similar price. It is really the x4 cards you would want to avoid. An RTX 3090 isn't compromised by a x16 PCIE 3.0 socket.

    This would be fine for a media server?
