Yeah, state of the art performance in a dumb media server is a waste of money.
It will buy you some bragging rights, and if that is what floats your boat and you have the coin, go for it, but be honest with yourself about it.
However, I would hate for someone on a more limited budget to read this and put money into processing power thinking they are improving their system, when they could be putting it into speakers, subs, screen, projector, room treatments, etc. - where they would notice a real benefit!
