And this is what companies like Orion are targeting.  Specific 
classes of users who need lots of computation, with a specific 
program, and with $10K to $100K to spend.  I don't know that there 
are "consumer" applications like this yet, but in the generalized 
engineering world, there are a number of finite element codes for 
electromagnetics, structures, CFD, and thermal analysis that are 
widely used.  These codes take quite a lot of computation, so 
something that is a truly "turnkey" speed up by a factor of 10 or 100 
is worth it.  Turns a "load and run the model overnight" kind of 
operation into a "run the model while I get coffee" operation.
