Hmmm, yeah, just twist my words as you wish. I never said that it is
power hungry compared to other workstation systems. I did not even state
that it is power hungry at all. All I said is that it needs power and
somebody has to pay for that too.

Now you show off with random numbers that make things really weird. 10W
for what? per chip? or per core? Whatever it is, I hope your office has
air conditioning. And than that "it's using less power than the older
Xeon", omg really? you're system is better than shit?
