But wouldn't vector calculations on database data be sped up? I'm
thinking of GIS data, joins across ranges like matching one (start, end)
range with another, etc.
I realize these are rather specific calculations, but if they're
important to your application...
OTOH modern PC GPU's are optimized for pushing textures; basically
transferring a lot of data in as short a time as possible. Maybe it'd be
possible to move result sets around that way? Do joins even maybe?
And then there are the vertex and pixel shaders...
It'd be kind of odd though, to order a big time database server with a
high-end gaming card in it :P
