I just bought a Gigabyte motherboard. I guess I'll manage to use it for Linux rather than throw the money away, but I'll certainly never buy a Gigabyte product again. See part of the story in my post at

For your own decision, I suggest you pay more attention to some of the things on the Gigabyte web site that I should have been more worried about when I was deciding which motherboard to buy.
See what utilities and/or BIOS updates are mentioned in the product page for the specific motherboard you're considering. (I foolishly stopped there). Then see if those utilities and/or upgrades actually exist on their web site and see if they can be used without Windows. The utility I would have tried based on the motherboard product page doesn't actually exist and similar Gigabyte utilities for other motherboards only work in Windows.
I always download and read the pdf copy of the motherboard manual before buying any motherboard. In the past that has helped me. This time I decided against another brand I was considering because that pdf file was not yet available on their website. I downloaded the motherboard manual for the Gigabyte motherboard that I eventually selected. The BIOS didn't seem much worse than the one for the ASUS motherboard I recently bought for my son. But the Gigabyte motherboard manual pdf file was a total work of fiction. The physical board layout was different from that in the manual. The BIOS had barely any resemblence to the BIOS in the manual.
Mine was not the same motherboard you are considering, so your results may be entirely different. But I suggest being very wary of that brand.
