This is the big debate right now. It's not about shader models. It's not about battery life. It's about 64-bit and dual core. These are the big buzz words being thrown around, but what do they mean? The salesman at the store tries to sell you a Turion 64 notebook because "this processor is 64-bit!" Well what the heck is that? "This is a Core Duo! It has two cores?" So that's like...having two processors, right? So that's twice as fast? Notebook users right now are in the unique position of only being allowed to have one or the other, a problem which desktop users handily avoided with Intel and AMD rushing out the Pentium D and the Athlon 64 X2, neither of which has bothered to grace the notebook platform except in twelve pound land monsters. So the question of "how can I be future proof?" effectively has two answers, both simultaneously correct and incorrect. I hope this article will shed some light on what each of these buzzwords means, and which capability you should care more about. It is without a doubt - and my editor even cautioned me about this - that this will spark fevered, possibly angry debate in the responses. I sincerely hope and expect that the debate will serve to further educate us. I'm certain it will also serve to prove how convoluted and swingy this debate is, too.
