I seriously doubt that a significant portion of the market will ever be able to afford multi screens and gpu's such as yourself. So I doubt developers would drive gaming into a direction where consumers wont be able to afford the product.
I personally think gaming is moving into the console direction...sadly. Majority of PC games are console ports anyway...
So building a 40k rig just to play battefield 3...I dunno, just does not make financial sense to me.
Valid point..
