Last year I tossed out HP's Z800 Workstation for the PC guys to drool over. Well it just got better and though it's out of the price range of many of VM's readers, the Z800 is now faster, more efficient power-wise, quieter and is not any more expensive than the original model!
For the serious gearheads on the forums the new Z800 has shucked off the twin Nehalem Quadcores and put on a pair of Westmere Six Core 3.33 GHz processors (yes, I said '6' cores.) There's much more but I won't spoil the 'drool factor'. Take a look at the article at Studio Daily for a look at the new HPZ800.
