[Naito]

Interesting point raised there. It's true though, those CPUs still would be adequate for most games these days. We've seen so many poorly optimised console ports and the likes. I wouldn't blame the developers/programmers, but rather the publisher for strict deadlines and budgets, and possibly ourselves, as we are the ones buying a large variety of devices that stretch these publisher constraints even thinner (though you cannot excuse studios like Activision with games such as Call of Duty; they'd be raking in the cash). As for taking full advantage of a CPU, you'd probably need to be getting down and dirty with assembly :P. However, that may be counterproductive.
