CSPI makes a VME based card (uses the Intel i860) that's rated at
something like 50 MFLOPS.  I have an old version that I think is rated
at about 1.0 msec for a 1024 pt. complex FFT (someone swiped all my spec 
sheets, but I think that's right).

The catch is that you need a VME bus expander in addition to the card.
Current pricing for the card is ~6K, I don't know how much our VME expander
costs in real money, but HP sells it.

There are some nice subroutine libraries available, too, though the more
extravagant stuff will cost you.  I was very pleased with the old card, and
their new one should be an improvement.
