TBH I've had very little issues with my pre-order launch board. I have used 4 differing CPUs and 3 differing RAM kits. I have also used every UEFI released after 0902 til 1501 except one or two.
I view threads for other mobos as well on OCN. I have found none that make me wish I didn't have a C6H.
The Taichi has had some real pants UEFIs, check out Buildzoid's monthly rants on YouTube. The K7 lacks many UEFI features that the C6H has. On the K7 also when changing RAM timings you enter 2 sets of values, one per channel. Then the K7 owners have been having bios brick issues, C6H was fixed on 10/03/17 for this. Plenty of owners of Taichi and K7 have issues as well.
I have non X and X CPU, other than the resume/sleep issue the X is fine IMO and the UEFI issue will get sorted.
