Last I knew, all TBred and Bartons were factory unlocked. If AMD has changed this policy recently, no NF2 board will "unlock" the processor. You're gonna need the good old conductive paint.
Word to the wise: people who don't know what they're talking about say the NF2 "unlocks" processors. Read up a bit on the issue and you'll understand. Hint: It has nothing to do with unlocking.
