yes, the cell processor is very powerful but only if the application is
optimised for it.

The cell has effectively a main core which is basically a PPC processer,
which is called the PPE and then 6 SPEs which are the floating math


When Linux runs, it only uses the main PPE core, which is very similar
to a 64bit PPC chip.

The 6 SPEs are not used, unless you specifically write your application
to use them.

Basicly: The cell processor is really, really powerful IF the
application is written to use the SPEs. It also requires that the
program uses the SPEs in the write way, the SPEs are best designed to do
vectorised floating point math, so programs that require this sort of
math (such as 3D games and physics engines) will gain a huge performance

If not, you'll get far better performance if you just use a standard x86
