Ehhh. I think this is a great idea! Some idea as the "SLI" or "Crossfire" that everyone seems to love. Why not bring out this idea. YOu know the possibilities of having 4 different cores to run on your system? Yes. This does mean very high prices, but why not for the enthusiasts?

Nah. Not a stunt. Just another idea to bring to the table. Something new. Something unheard of. I think it's a spectacular idea.
