If you are not having a problem, I have always said don't update.
Because a driver or bios is out there and it is the latest that doesn't mean you have to update too it.
I'm not telling you not to update your drivers. That is up to the person and their motherboard.
They are maybe getting the updated drivers from the makers like Intel, Realtek, & Marvell.
The site might be Ok and that is up to the person that wants to use that site. I'll stay with Gigabyte.
Most motherboard companies don't stay on top of things too.
My drivers Dates are Network 07/11, Sound 08/11, & Marvell 08/11
