"The new Z840, Z640, and Z440 desktops are more quiet and power-efficient than their predecessors, but the big news was the support for 36 processing cores on the Z840 and Z640. Yes, we all asked if the number was a mistake. HP showed us the system monitor, which displayed a total of 72 threads (doubling the core number via hyper-threading)."
Wow, that with WD's new 10 TB drives would be quite the workstation. Might need to upgrade my Wintel box soon ;)
