When I play console games on my Xbox 360 the biggest annoyance by far is the loading times. You run around in Skyrim and you enter a house so you have to wait 30 seconds for the content to load. Then you leave the house and have to wait 30 seconds again. My point is that the relevant performance metric isn't speed of number crunching anymore - it is speed of transporting data from one part of the system to another.
