Your example uses GTX1080, which is a very old GPU. Current flagship consumer GPU will take a harder hit on low bandwidth PCIE.

Here’s more recent HW: https://www.pugetsystems.com/labs/articles/impact-of-gpu-pci...
This is an RTX4080.
“In the more common situations of reducing PCI-e bandwidth to PCI-e 4.0 x8 from 4.0 x16, there was little change in content creation performance: There was only an average decrease in scores of 3% for Video Editing and motion graphics. In more extreme situations (such as running at 4.0 x4 / 3.0 x8), this changed to an average performance reduction of 10%.”

A 10% performance reduction seems like a lot to be leaving on the table.

The article is nearly 3 years old and the 4080 is not even top of the line at the written time.
Still, 10% in difference is still considerable, almost gen-to-gen difference
