My very wild guess, PS3 is no longer significant for this kind of task.

Based on some wikipedia reading:

http://en.wikipedia.org/wiki/Life_with_PlayStation

An "old new" version of F at H for PS could deliver about (1500000 GFlops / 
52000 users) ~= 29 GFlops per one PS3. Five years ago, this was 
significant. Today this is not so impressive, when compared to new CPUs, 
or even old ones (green is for GFlops):

I would expect even better performance from GPUs. Given that they have a 
deadline for every workunit, a slower cpu is going to decrease 
performance of the whole project.

As I say, just a guess.
