Well, we stuff lighter cards (think 8500,8600) in our vision systems
(passively cooled is better for factory use).
We are also playing with CUDA, but one of the problems we have is that you
must do pretty heavy transformations to earn back just the transfer of data
to and from videocard memory. Those are too rare for us to dive into that
technology quickly, but I'm keeping notes :)
However if one is more pattern recognition oriented, I can understand that
it could get interesting.
btw, is CUDA MT, as in that you can have several independant calculations on
the same GPU ?
