Realtek 8111e vs. Precise

> Anyone have a recommendation/preference on ASUS vs. ASRock motherboards?

Asrock has great quality and great prices. I like Asus, but I rarely buy
them now that they are in the upper price ranges. 

By the way, I've been using a few different brands recently and found that
if an option in the bios named 'iommu'  was enabled, the network card ceased
to function for Ubuntu.

There are other bios options like UEFI that have to be set just so, as well.
