gen3vsgen4

Hello guys, I'm willing to upgrade my GPU to RTX 3080 (Colorful iGame). I have Asrock Z490 Taichi which is a Gen 3 Motherboard and Intel Core I9-10900K. Asrock says that they support gen 4 features on this board. So my question is if i buy RTX 3080 will this gpu run it with PCIe gen 4 features...
