I have both a UD5H and a UD3H and I must say they are an improvement from the p67 - Z68 - X79 chipsets! Gigabyte got behind by going with the hybrid bios.
A lot of issues still need to be worked out with the USB functionality though! The XHCI adaptability seems to be flawed. This includes all options smart auto/auto/enabled etc..A new bios update solves one USB problem but creates another. Maybe blame this on Intel but I do not think so. Asus boards have a better acceptance of different USB Product manufacturers and I can say the same for MSI.
To fight a USB acceptance issue for hours that was not experienced on an Asus and MSI product causes some concerns.
I use high end gaming keyboards and mice down to the basic products.
I use all operating systems in my endeavor but I have also experienced greater issues with USB in the mainstream Windows 7!
I wish I had the time to compare different USB products with different manufacturers but it just is not possible at this point! I am trying to get a couple of review websites to make this comparison though!
Just a concern from a longtime Gigabyte user!
