    i7 by far, since sony vegas supports multi-core.

    Ah, the good ol' quad vs dual debate.

    For what you are doing, the i7 is far better. Video encoding will be leagues easier on the i7.

    the dual is 2.8ghz and the quad is 1.6ghz. Wouldn't the dual be better?

    <s>2 * 2.8 = 5.6

    4 * 1.6 = 6.4

    And in this case, the 1.6 is faster clock for clock than a 1.6 C2D, meaning that it would be closer to 1.8 to 2.0 * 4.

    Toss in hyperthreading if supported = 1.6 * 8 (but not quite) </s>

    Simplified analogy for explanation sake.

    turbo boost is intel's OC'ing. or so i think. 720 goes up from 1.6 to 1.7.
    on 2-threaded apps, the 720 can turn off two cores and run the others at 2.6, 2.8 with turbo boost.

    beats the t9600 hands down.

    No. CPU's do not work like that. It is not 1.6Ghz x 4, or 2.8Ghz x 2.

    But the technological advancement means that the i7 has a far better architecture, also has Turbo Boost, and with more applications these days that are 4 core enhanced, it's an upgrade that is certainly worth it.

    I know it doesn't work like that. lol, but it was the easiest analogy. Especially with the assumption that
    and with the fact that the program in question supported multiple cores.

    That's good then. I can't count all the people that actually believe this to be true...

    Theoretically the performance scaling of multiple cores should be linear, if the program was written with parallelism in mind. If you look at wPrime benchmarks, two cores performs the calculations twice as fast as one core.

    I would get the laptop with core i7 but i would personally get a desktop replacement with core i7 desktop processor...no problems at all then :)
