Looks great (if you believe their white papers) if you're planning to
run BLAST.  Doesn't look horribly shabby at floating point performance
overall, has a nice peppy FSB.  I certainly wouldn't kick it out of my
system room for chewing crackers.  So to speak.  Although I believe that
it requires some fairly careful programming to get maximum speed out of
the CPU and would be very curious about real-world benchmarks for code
that is just slapped on it and compiled, no tuning or hand
vectorization.

However, the traditional litany requires that one examine price as well
as raw performance, and comparing it to P4 (really P6) class CPUs is
apples to oranges.  A more interesting and fair comparison would be to
opterons and itaniums, and including price.
