And if Intel actually manages to come out with more than repainted and renamed CPU next year that that Z390 likely won't take it.Seems z390 will use the same socket but will be a full chip feature like H370 and VRM count to match - though i bet it'll cost and arm and a leg!
For many years CPU development was so slow that upgradeability really didn't matter.
But now situation is different and when upgrading from Haswell I'll certainly put value to CPU upgrade chance.
