To many Pixels is counter-productive!

Unless you have a GPU card, your image processing will not be faster with 32GB RAM.

Putting few layers of high mega pixels pictures together will easily eat up the RAM.

More megapixels doesn't mean more dynamic range. The camera maker need to design the processing engine to transform the extra megapixel into dynamic range.

For example, the Nokia 808 high pixel count 41 MP is to allow the 808 to produce better quality lower-resolution images (3MP, 5MP or 8MP).

If the camera maker didn't transform the additonal pixels into dynamic range, what you get is just a large picture with same dynamic range of a lower megapixel picture.
