The Gigabyte board is probably the current overclocking champ for socket 1156 mini ITX. I've seen reported clock speeds that my DFI board can't touch. Now, of course this board has only been out since earlier this year and I don't know how many of those 4.5GHz overclocks will remain stable in the future, but that's just the risks inherent in overclocking. Oh yeah, and I think those huge overclocks might be with dual cores (i3/i5) and not necessarily the true quads.
