Quick answer.. gotta go to work

Jack, i never said high resolutions will gives a bunch of more CPU utilization then high ress (if i got you right). My intention was do clear out that a Intel Core CPU will always give you a lot more overall fps in low res just because of their power when l2 cache and prefetchers does it best. And that this higher Frames will cuted off in high Ress just because the Card acts like a framelimiter and allows you to focus more on the low FPS.

To get away from the resoultion :

Lets take a game where the sweet spot is around 60 FPS (min FPS around 30 max FPS around 90). The AMD will max out the graphic card to around 60 FPS an Intel will go up to 90. Enable Vsync to 60 FPS and the overall higher FPS over 60 will be cutted off. So there is more focusing on the low FPS. Run the game with different CPUs (or Platform) and lets see which handle the critical situations better.
