Not that it means much to me at the moment , as I have no hardware to utilise the standard and likely won't untill new PCI-e SSDs show up with the standard but if Asus do not release bios updates for PCI-e 4.0 on X470 and gigabyte do than in future I'll no longer use Asus in my builds. Between their poor excuse for after sale support , RMA process and overall tax on hardware and then on top lack of legacy support on hardware this would be it's finally outing in my PC.
