>so a limit of 4 does seem reasonable
I have a Fujitsu Celsius R650 workstation dating from 2007 running XP Pro x64, it has dual quad-core Xeon's. The 2012 R670 gave the option of dual Xeons with 6 cores/12 threads and a choice of XP Pro x86 or x64, Win7 Pro 64 or 32.
So it would seem MS don't really want this version of Win 10 to be used on high-end workstations, unless they mean a maximum of 4 physical processors...
