You may have done better service to the readers of this list than you
have to yourself, since the readers of this list are naturally inclined
to think about the sort of question you have asked, and the answers have
been interesting to read.
The fact that you are asking the question, though, begs an answer that
others have partially given: no plausible hardware purchase you can make
will be a substitute for you or someone you are working with to get
smart about being clever with hardware and software. You don't want to
invest in people, but people is what you must invest in. There is
probably someone out there really hungry for work or just plain
interested who could get you an awful lot of mileage for the money you
want to spend.
Without that sort of expertise, the chances of your getting much further
than you already are through a hardware purchase are, to a very good
The application you describe sounds like something that might wind up in
an ASIC or FPGA, but that involves serious people time.
The only no-brains speedup strategy that could work is the most powerful
speed-up strategy of all: wait a couple of years for off-the-shelf
hardware to get faster.
