Any suggestions or changes for this build before I order?

Intended use?

Even if this is just mostly, vs primarily for gaming, I usually tell people the X platform is a waste of money.

1. The 7820x is same clock speed as a 8600k that MSRPs at only $259
2. The 7820x turbos on only 2 cores, vs all 6 cores on the 8600k.
3. Unless you NEED all those Pci-ex lanes, the X MBs are too expensive
4. A Z370 MB has 24 Pci-ex lanes just via onboard Intel chipsets, and would easily handle your 1080 Ti on an x16 slot with more than enough lanes left over for your NVMe drive.

Aside from that you're specing a PSU that is 400w more than you need for a single 1080 Ti, and 150w more than you need even for...
