Will the 2600x/Asrock X470 Master SLI/Gskill 16gb 3200mhz(f4-3200c16d-16gtzb) be a good combo?

Solution
what do you need on that X470 while B450 can not provide?
If that X470 is a must-have, sure it is a good mb and good combo. If there is a big price diff, you may get 2600 and OC it to similar level.
