the advantage for pci-e generations isn’t the gpu side, but SSD side(USB too). CPUs by design, have a limited amount of PCI-E lanes they can distribute. Modern SSD’s primarily use 4x pci-e lanes, but if you have a generation newer, you can allocate half as many lanes to achieve the same speed.
Since at the moment, the value of even faster SSD’s are useless, what ACTUALLY becomes off value is having multiple m.2 slots for expansion. for example, instead of having 1 m.2 running pci-e 4.0x4lanes, you can achieve the same speed at pci-e 5.0x2lanes, or pci-e 6.0x1lane. Using less lanes on m.2 slots means you can allocate more bandwidth to other components(more m.2, more USB ports, etc).
this for eaxmple was the reason why experimental gpus like the Asus Dual RTX 4060ti existed, as its a 8 lane gpu, which had an on board to use the other lanes as ssd storage on motherboards that supported bifurcation.
We can’t get decent video cards hardly at all let alone something that would use this.
