if you got yourself a matrox parhelia video card, you'd have 10bits per colour channel for true 30 bit colour. the extra 2 bits per channel make your display go from 16.7 million colours to a few billion. With that, you can say goodbye to colour banding. incidently, 32 bit colour is really just 24 bit (8 bits per channel) plus an 8 bit alpha channel. Ad that alpha channel to the parhelia and you have 38 bit, mwahahaha!!! hmmm, that card's been on my wishlist for awhile...
