How often do you "unexpectedly need to scale out"? By an order of magnitude at least that is, because under that you could add a few more of those beefed-up machines.
I wonder what happened with YAGNI principle. It has arguable uses in some places, but this one it seems to fit perfectly.
I've had such a situation and we were lucky that we had written software that makes dealing with embarassingly parallel problems embarassingly scalable.
