If ASUS does not make the Armoury Crate program available for the MAXIMUS X series, it's a shame, my brother has an MSI board of 80$ with about 2 years, and there are updates to the driver program etc, the update MSI program drivers is much better than ASUS.
I think by the amount you pay for a MAXIMUS X CODE ($ 350) that is just over a year old, ASUS should give other customer attention in terms of support.
And I do not believe Armory Crate does not work on a MAXIMUS X.
