Armoury Crate allows you to update a few things, that as far as I am aware, can't be updated anywhere else.
Other than that though, it is pretty much useless. Unless you love RGB lighting.
The main purpose of the software is totally broken, updating drivers and utilities. Most of the time after a restart, nothing was updated or installed. Especially with regard to AISuite3. Trying to get that installed from ArmouryCrate seems to be impossible.
