But couldn't that also be seen as a chicken/egg situation?  No-one
buys GPUs for database servers because the database won't make use of
it, but databases don't implement GPU functionality since database
servers don't tend to have GPUs.  It's more likely the latter of those
two reasonings would have to be the first to budge.

But nVidia does produce a non-graphics-oriented GPGPU line called
Tesla dedicated to such processing.
