Hardly a good comparison. A single-core vs. a dual-core, an un-overclocked to an overclocked, so many things wrong with it. AMD is hardly in trouble, games aren't really CPU dependent. Most of the problems fall on the video card.

It's not about whether we want realistic characters in our games or not, it's the amount of content it's going to take to make them look realistic (Many animations, for example). Ubisoft seems to be on the right track of getting out of the valley. Oh and Gamespot you're late. The Wiire had an article about this a while ago :P
