Magic, but wholely useless
It's all good to say the PC is becoming magical again but extremely powerful graphics hardware is practically useless when game developers are dumping the PC platform like yesterdays newspaper!
It's no wonder nVidia and ATI are starting to focus the extreme number crunching performance of a GPU into other non-game or graphical related tasks. They see the writing on the wall and have started to branch out into other areas. What I feel they (or possibly myself) are missing is the scope of this redirection of focus. Apart from some minor assistance in the graphical content creation and encoding areas, for the majority of consumers GPU processing isn't really usable.
While diversification is a good thing for business, I would also be trying to slow or reverse the migration of games to games consoles. I can imagine in the console graphics chip world, nVidia and ATI have the margins on each chip negotiated to within an inch of their life, where as the markup on consumer chips would be much better so why not try and keep that market alive.
