    im a little confused here on which is better (the title doesn't really match my thread, but i didn't know how to describe it)
    a high GHZ C2D, like that super power one thats 3.1Ghz or a low GHZ which i've seen in a lot of dell notebooks, like a 1.6ghz one.
    so which one would see more improvance in everyday tasks and which one for heavy tasks such as movie/photo editing?

    The 2.66 i7 will be much faster than the 2.66 C2D. This is a difference in architecture and a few other features that it includes. They both have two cores and are the same clock speed, but the i7 has turbo boost, hyperthreading and a 32nm process rather than 45nm.

    The i7 can turbo past the C2D in most cases (GHz).

    The i7 also performs better per a GHz.

    The exception to this is the i7 low voltage series, which pretty much just goofs the naming scheme.
