Greetings,

Here is a video of a rather impressive Manifold GIS CUDA demo  
performing a raster operation:

http://www.manifold.net/video/nvidia_cuda_demo.wmv

The operation is reduced from 60 seconds to 2 using 1 GPU - imagine if  
they had 4 GPUs! It would go from 60 seconds to nearly realtime....
