Probably be better waiting for windows 11 to come out in 6 months. Ive seen they are saying the pcie x4 drives will work substantially better than pcie3 nvme with windows direct storage, but who knows until win 11 is actually released. Pcie4 drives cost a lot more though
In the meantime there is little difference in real world gaming gaming between ssd and nvme, unless you are upgrading from sata HD
