>MS revealed at E3 XBones RAM utilizes 5 Gb for gaming, 3 for OS, so they did tell us how it is going to work.
Also you just made a comparison about a graphics card in an office suit, against next-generation graphics RAM for a video game console. I don't know if you've noticed Jet, but video game consoles are made to be able to play video games well, and having a lack in hardware isn't exactly going to help that cause. There is no comparison there. A comparison would be an PC manufacturer selling an Office PC with a full office Suit, and a competitor selling an Office PC with half of an Office Suit, but the competitor has a lot more features that you can buy on top of what is available as well is more expensive for the ability to buy those features. That's the only comparison that can be made there, because talking about an Office PC with a next gen GPU versus RAM in a video game console that NEEDS TO UTILIZE IT is COMPLETELY different.
