Intel releases Firmware updates to manufacturers for a reason.
Other manufacturers have updated their X79 boards to install the latest Intel Management Engine Driver versions 8.x.x
Gigabyte too updated the firmware on their Z77 motherboards BIOS updates.
The X79 boards from Gigabyte are far behind.
The list of bugfixes for the Intel Management Engine at both Firmware and driver level is pretty big and includes all sort of issues that Intel sorted out thru time, just like this out of many documents shows:

The Intel Management Engine firmware update must be provided by the OEM which means the motherboard manufacturer.
And Gigabyte is far behind supporting X79 motherboards now.
Manufacturers release updates for a reason.
If you don't want to update your machine it's your fault. A machine can look stable but the bugs are there and without the updates you don't know when one out of the many unfixed bugs could kick in and cause issues.
Updating continously without having checked that the updates are stable and the manufacturer didn't pull them or released another quick fix would be dumb and unprofessional indeed BUT not updating machines drivers and firmwares it's just lazy.
Sure it can take time to update hardware and software properly. But at the software level anyone should always make a system backup to avoid any possible issue so that it's possible to revert back if a whole re-install can't be performed in a business environment.
