Well, there's almost no end of applications that wouldn't be improved
or made usable by a hundred-fold increase in CPU. But things that aren't 
currently possible for commercial or domestic use might be;
In processing, blind source separation using dictionary attack to find 
optimal sparse decomposition; also similar to deconvolution or upmixing
without prior models. In modelling; for wavefield modelling or lumped
masses with a large number of nodes. In analysis; articulatory speech
models to do speaker independent recognition. 

The practical outcomes of the first group of things are basically
being able to record an orchestra with a stero mic, pull out and process
individual instruments after the fact, change the hall acoustics and remix 
the recording. The latter stuff is more obvious, raytracing reverbs and

But being unable to brute force these things leaves the quest to 
understand deeper and find optimisation tricks to change the
algorithm/approach, not matters of scale. When the growth order
of a method is wrong throwing a room full of GPU's at it only
gives you a temporary lead.
