Yeah, they used Fermi back in Dec 2011 since Kepler was no where near ready. They upgraded 10 cabinets, called TitanDev, to test out their code, CUDA.
I'm sure they received a number of early/ES GK110s at some point but there really is no documentation of that.

Oakridge supposedly received ~32 K20x at the beginning of Sept.

The article states they were planning on receiving about 1k more that week, I would assume it was a couple thousand before the 13th of Sept.

They started installing K20x for the Titan upgrade Sept 13th and finished sometime in Oct.

They didn't finish acceptance testing until 11th of June 2013, since Cray had to repair all the mobos.

Edit- Ahhh... don't talk about wafer pricing. Highoctane will go crazy if you imply a new node is more expensive per wafer than an old node.
