I'm a DARN noob in computers, so please don't flare me for this one. My last post was about my dad wanting to buy a laptop. Well, he (and I) are confused over the cores and whether it will effect the laptop computer's speed/performance. E.g. Laptop A 2.3GHz Dual Core Laptop B 2.0GHz Quad Core Are these laptops equally fast? I went to a store and they said these numbers contribute to the speed. I'm really lost now. Thanks.
