Great, if you think you need "Thunderbolt." Even greater, if you think (as I do for the moment) that ASUS is building some great motherboards. But when it gets down to bang-for-the-buck, I'd look at several Maximus versions and and some of the more modest ASUS Z77 options, with an eye toward what it is I want and need specifically.
The Maximus V Extreme is the only ROG board with built in Thunderbolt. Asus has two Maximus V Formulas, one with the ThunderFX USB sound device and one without.
I think he was just linking the review so others would see it. Though that same review was listed in the news sections daily review roundup a few days ago.
