I guess what I'm wondering is whether there is a sweet spot in the
price range. Are the Quadro 4600\5600 series worth their exorbitant
price tags because of their larger memory and 'workstation optimized
architecture', or is the cheaper GTX 200 series better because of
their larger number of stream processors?

In other words, does the general IDL performance scale directly with
the number of processing units times clock speed, assuming there is no
bottleneck loading the data into the video ram?

I also see that the GTX200 series supports limited double precision
operations, which might be another trump card.
