Marco Arment:

The new Mac Pro feels very expensive when configured with a few options, and it’s easy to feel that it’s much more expensive than previous Mac Pros.

And it is. But the big jump actually started with the 2009 model, when Intel started running out of ways to make the high-end Xeons better except by raising their core count, which drove the price up dramatically.
