You have to give props for Asrock as they are frequently offering unique motherboard features (like that mini-ITX X99 etc).
However, it still does not change the fact that Xeon v3 models are slower(tops at 3.9Ghz Turbo) single threaded than Haswell-E, so it is the same story just a different chipset, either you get fast single threaded performance with Haswell-E or you get Xeon with ECC.

Take these somewhat similar chips: http://ark.intel.com/products/82931/Intel-Core-i7-5930K-Proc... http://ark.intel.com/products/81900/Intel-Xeon-Processor-E5-...
Why can't we have 5930k with ECC support? Because then some thrifty IT managers would buy those for their low end server needs.
