Slight differences in CPU clock speeds: Yes, a 2.6GHz processor will be faster than a 1.2GHz processor, but you shouldn't pay more for small increases in clock speed. You won't notice the difference between a 2.3GHz Core i5 and a 2.5GHz Core i5, so don't pay $100 for the privilege of an unnoticeable uptick in processing speed. Related:
RAM speeds: Again, faster is faster, but the noticeable difference between 1066MHz and 1333MHz is practically none. Related:
DVD/Blu-ray write speeds: Even if you are one of the handful of folks left tinkering with physical media, you'd be hard-pressed to find a drive that offered much of a leg up in burning speed. If you're going to burn a disc, you're going to be waiting a bit whether it's a 6X drive or a 10X drive. And they all play movies just fine. Related:
