[hpsdr] Calculating engine

And,

Not all functions are supported on older NVIDIA cards. There's something
called 'compute capability', from memory you must have compute capability
3.0 or higher to run the CUDA SDK's FFT.

A decent 2009 i7 system is not too bad although it could be a bit power
hungry. Myself, I would think about replacing the video cards with something
like a GTX 950 as it'll be more powerful than the cards in the tower, will
chew up less power and supports the latest CUDA SDK. With the 1080 / 1070
announced there will be a lot of the 9xx cards available at attractive
prices.

NVidia's CUDA, their API and libraries for using one or more GPUs as
computing resourcese, was first released in 2007. That gaming computer from
2009 is likely to be capable of using it. On the other hand, the amount of
computing it can do per watt won't measure up to more modern cards,
especially the upcoming GTX1070  and 1080.

Still, if the price is right...
