Right now I am waiting on the successor to the 2080 TI to upgrade my graphics card, and at the same time will either upgrade my processor to a 3900X or, if AM4 still supports Zen 3, buy something from the Ryzen 4 line. What I am curious about, however, is how close the current top end card (2080 TI) is to saturating the PCI 3.0 interface. I know it's a bit early to be thinking about this, but I'd like to hold on to my current motherboard for another 3 graphics card upgrades (i.e. 5 years upgrading every other generation) and if top end performance increases ~30% each year I am trying to ballpark whether or not I can do that with my current motherboard/memory, or if it is better to upgrade to PCI 4.0.
 
Even 2080ti is far away from saturating pci-express 3.0 bandwith.
 
Extremely far.

like if you switch it to to PCI-E 2.0 you won't notice far.
 
PCI Express 4.0 will make SSD speeds faster etc

Yes for a simple reason:

PCIe 3.0 x4 has a max bandwidth of 4 GB/s, and PCIe 4.0 has 8 GB/s.

PCIe 3.0 x16 used by GPUs has 16 GB/s max speed and PCIe 4.0 x16 will have 32 GB/s.

You can run PCIe 4.0 SSD which can do 5 GB/s but on PCIe 3.0 x8 slot
