    So what are the speed differences between a C2D 2.66 Ghz and the 2.4 i5 found in the new macBook Pros?

    .26 GHz. Real-life difference depends on what you're using it for.

    the i5 is quad core, C2D is dual core ;) the speed difference is negligible

    The i5 is about 20% faster according to the Passmark CPU score.

    The i5 used in the MacBook Pro is dual core, quad thread.

    Actually it's still dual core, but the speed difference is still negligible.

    you are mistaken

    the i5 is also dual core for mobile purposes

    I am thinking to buy the 13inch high end model but could not decide yet.

    What would be the performance difference between high end 13inch and low end 15inch

    2.66 Core 2 Duo vs 2.4 i5 ?

    I am not a gamer, just for surfing, music, media, movies, aperture, photoshop, office apps..

    I want to know the real world difference, I will not play games except Starcraft 2

    Save the $300 and just get the base 13". The .26GHz is essentially nothing unless you need seconds saved. The hard drive you can upgrade yourself later on if you need to, which is a lot cheaper than the price difference.

    Then the new mbp will suit u better. The 320m is better than the old gpu. The i5 is thinner and therefore uses less power so longer battery life.

    Before you mentioned sc2 I would have said the c2dou would be fine.

    I do not think that Starcraft 2 will need a lot of cpu or gpu power? Though, it is just a real time strategy game, we are not talking about FPS games :)

    I do not like the bulky 15inch notebooks, they are not light.

    U ever see some rts games running on full detail in hd? They look insane and also take a bit of horsepower.

    The CPU itself is thinner tho and that results in longer battery life, regardless of if you game or not

    If this is it, even my C2D 1.66Ghz HP Pavilion can run it now !

    I think 2.66 and m320 will be enough for SC2, that is the only game I will play. Morever, I will not use an external huge monitors with it. Full resolution, med details are just fine.

    It is just pshyclogically annoying to see C2D in your computer while the new i5 architecture has already come in to the market...

    I really would not mind it if the difference was up to 10% but we are talking about 20% :confused:

    I don't even really think you'll notice the difference that much, are there apps that take advantage of the extra i5 threads now?

    And if there are I'm sure you'd be using something top of the line not a 13".

    the i5 processor is 2 cores 4 threads, people seem to mistake cores to threads alot now:rolleyes:

    but the difference should be significant, and alot of people seem to forget about turbo speeds, the 2.4 i5 gets clocked to 2.93 on turbo speeds, which is pretty significant i wouldn't risk the old tech,and try to justify it with size, plus you can get HD screens on the 15", that sold me :)
