ne pesimizmo, o realybes :) .. C23X nera "desktopines".. joms ir lenda..
By default nuo senu laiku C2xx imdavo celkas/pentium/i3/E3, nemego i5/i7
Cia patikslinu, kad C2x6 "6" = workstations, imdavo viska ir i5/i7

source wike:
https://en.wikipedia.org/wiki/Skylake_(microarchitecture)#Features
Unlike previous generations, Skylake-based Xeon E3 no longer works with 
a desktop chipset that supports the same socket, and requires C230 
chipset to operate.

H1xx - home
B150 - business (entry)
Z170 - entuziastams
Q1xx - corporate business
C23x - workstations/servers

Gal kur persiplaka toks pozicionavimas.. ir jei aktualu, tarkim:
