FPGA performance on various algorithms is already 1 to 2 orders of 
magnitude (e.g. 10 to 100 times) faster than single CPUs.  The price 
points of modern FPGA boards with modern algorithms is about 2-4x single 
node pricing.

As FPGAs improve (and they are), expect to achieve significantly more 
performance.

Hmmm.... HMMer was parallelized using PVM quite some time ago, and using 
MPI quite recently (with excellent results reported).  GROMACS also has 
been parallel for a while.

Gromacs: http://www.gromacs.org/benchmarks/scaling.php
HMMer: http://hmmer.wustl.edu

Amber and many other MD codes have been parallelized for a while now...
