newmat vs boost

[cj-wijtmans]

First of all if the case is the GPU is busy doing 3-D rendering CPU will most likely be at 100% if there is a multicore CPU, than the cores will be busy with other threads, even if they are idle.

and its not reasonable to assume that there is a 3D app running while doing complex heavy processing.

multicore CPUs will be alot worse in data-processing than a single core.

GPU's are really good at processing large ammount of data, it will be a rare case that in this situation a new GPU will lose against a new CPU.

CPUs are really to process the multi-task system while GPUs are for 3d processing.
There are also cards available that are for physics processing. In the end the best soluttion would be a new card just for doing data-processing, but i dont see that happening.
