There have been products like that for video input (tuner via USB etc) -- I think the reason you don't see similar products on the output side is that it doesn't make much sense to separate video output from 3d output since they both go to the same monitor.
The other, more practical problem is that the chip design is often largely finished while the video standards are still in flux, so the only way to have *all* the video processing on chip *and* maintain the required flexibility is to give the chip a big general-purpose processor, and that raises the cost of the whole system.
We are obviously heading in that direction with Fusion, but that will eliminate the need for a separate CPU at the same time.
I'm not following you here...

As for adding expense, yes, it would. But there is also an offset in cost-per when a device has a longer life cycle, even more so when gross profit is less important than overall function and the future of society as a whole is more important. And the discussion digresses to business philosophy more than technical aspects of design.
We, as a society, aren't there yet in terms of social cooperation, but eventually we will be and it does no harm to examine future strategies. Some of which can be implemented in whole or in part, now.
From my point of view we really need to break the crippling dependence between a mfg's hardware and a specific OS's driver/software and the linkage at the moment is the bus. A next generation, command driven, analogous clock rate (analog waveform, digital pass-filter), multiplexed serial system bus would go a long way towards such independence.
But, it would require cooperation and public support for standards, something the leader in the software industry has shown to be less than willing to be part of, having been sued in nearly every major jurisdiction on the planet for "unfair business" practices.
But one man does not make an army...
