having just talked to somebody who uses 32 PS3s for computational work (and uses a myriad of Teslas for their work also - she says that the Teslas are many many times faster then the consumer models, and that F@H really can take advantage of the bandwidth/memory/frequency increases of the cards. make of that what you will - its extremely hard to find solid benchmarks.
32 PS3s! dang! i bet that was an interesting conversation.
well if i had a tesla, i wouldn't know how to get fah to use all that power. all i know to do is run the gpu client
