I have just read about the new programming environment for graphics processors. This opens up a whole new world for intense applications, and this power can be used for things like financial modeling etc.
CUDA 2.0 is the new C based programming environment for this new technology. You can download it free of charge here: http://www.nvidia.com/object/cuda_home.html.
This version also includes an Adobe Photoshop plug-in example for both PC and Mac versions of the software, which allows developers to design plug-ins that move the most compute-intensive functions of Photoshop to the GPU, such as filtering and image manipulation.
