When it comes to mobile processors, you have options – many options, in fact. If you're unfamiliar with your choices, or simply don't know what you need, it can be a bit overwhelming.
Further complicating the decision-making process is the fact that you can opt for both dual core and quad core processors. The assumption is that the quad core processor will always be the better bet, but that isn't necessarily the case. And this is because a dual core processor can be had with a faster “clocking” speed than a quad-core counterpart; additionally, many programs and applications aren't designed to make use of multiple cores, so that extra processing power isn't being put to use.
