How good (or bad) is the ASRock X99 Extreme3 motherboard?

Hi All,

Has anyone got anything good or bad to report about the ASRock X99 Extreme3 motherboard (http://www.asrock.com/mb/intel/x99%20extreme3/)?

I plan on hooking this motherboard up with an E5-1620 v3 (R2) processor and 16 Gigs of HyperX RAM (HX428C14PB2K4/16). Both the CPU and the RAM are listed on the official support lists...

Any opinions or personal experience will be greatly appreciated.

Kind Regards,

Davo
