HailMary, the FX line is also multiplier unlocked... and even now, the FX-51 isn't that far ahead of the 3400+ on most apps.
We'll have to see what they say, but I wouldn't count on it yet-- seems unnecessary to me... even if they can bin at 2.6, they'd have a lot more parts at 2.4, most likely.
OTOH, the dual channel for Newcastle may narrow performance so much that you could be right.
