Xeon based DAWs offer no real benefit for 99.9% of end users... and the cost sky-rockets vs. socket 2011/X79.
How many end users need more that 64GB RAM and 12 virtual cores at 4.5GHz?
Got a call from a composer in LA who had a local person build a VE Pro Slave (via LAN) to use along with his Mac Pro.
The local person built a Xeon based machine using an EVGA motherboard with a non Intel LAN controller.
Impressive specs... cost a lot... but doesn't work for the intended purpose.
