The two things a supercomputer needs are lots and lots of double precision FLOPS, and lots and lots of bandwidth to feed them.

It doesn't have double precision (only single) and, as HindiDiscoMonster pointed out, insufficient linterlinks to supply the bandwidth.  If you really want a supercomputer, try buying an AMD6950 (or Nvidia 680 or 780) and writing something seriously parallel (although with ~3G of memory, other supercomputers will kick sand in your face).

Basically, single precision is only good for problems that can be solved in real time.  Doing an FFT on audio data to 32k of samples sounds pretty bad just due to accumulated rounding errors.  Trying to do real supercomputing is just a joke (but might be great for serious DSP jobs).
