I know I dont need it for the gpu. but I have to set my pcie speeds to 3.0 in bios so my 5700xt doesnt crash. that also slows down other pcie 4.0 devices in my system to 3.0 speeds. so if I went with pcie 4.0 ssds they would be limited to 3.0 performance because my gpu is on 3.0Once again - you don't need pci-e 4.0 riser yet for the GPU. It'll start making sense once the new games streaming a lot of data to the GPU directly from m.2 SSD through pci-e will come out, so this means PS5 and Unreal Engine 5 titles at this point.
Right now it's just 1~3 % difference in performance and buying riser based on this right now is simply bad idea because once those titles come out the riser that states 4.0 compatibility right now might cause issues with the actual reasonable use that is that data streaming in the titles that are not there yet. We are on the bleeding edge for the pci-e 4.0 risers right now and we don't know yet what future proofing actually means.
