5.0 has double the bandwidth of 4.0
4.0 has double the bandwidth of 3.0

5.0 X 8 = 4.0 X 16

5.0 has double the bandwidth of 4.0
4.0 has double the bandwidth of 3.0

5.0 X 8 = 4.0 X 16

so, if i were to put in a pcie 4.0 gpu, and the slot it was in ran at 5.0x8, i would not see any noticeable lag?

That GPU would run at PCIe 4.0 x8. Would that impact? Depends on the GPU, but generally, there is no performance degredation.

What motherboard, and video card.
It takes about a 2080ti to show any difference in PCI-E 3.0 X 8 and 3.0 X16.

Not really enough information (future amd gpu) in general don't stress over it unless your going to buy the very top end video card.
