Now the one advantage of going pci-e 3.0 for the chipset instead of pci-e 4.0 is the fact that you don't need a fan for the motherboard but since the uplink is x8, you can still have some of the flagship goodies like multiple nvme and additional usb ports and etc.
But then you get the Dark Hero and lul at Intel fanboys.
Thank you Asus
