    I'm going to buy this new toy.
    Any idea of whether the upgrades of RAM and processor speed are bloody needed?

    I'll go with Duo and upgrade the graphic card though.:rolleyes:

    The 3.33GHz is 9% faster.

    I'd get the quad mate, there's not much monetary difference unless I'm missing something (or you want the 3.33GHz), you basically get 8 cores (4 physical + 4 virtual) compared to 2...
    $2249 27.5" dual core @ 3.33GHz w/ 8GB RAM + ATI Radeon 4850, $2399 @ quad core i7 @ 2.8GHz (turbo boost to 3.46GHz) w/ 8GB RAM + ATI Radeon 4850.

    It's up to you, but the quad seems so much more valuable.
    (Excluding Apple care)

    Kind Regards

    Thanks for ur advice. it does seem that there's no huge difference in money. I'd have known that before i make payment... How do you get 3.46GHz btw?

    Turbo Boost causes your processing cores to boost up to 3.46GHz when the other cores are inactive, say if your not using all of your 4 cores, the ones that are being used will be OC'd to 3.46GHz.
    They go back down to 2.8GHz when they are all being used, found this on the tech specs sheet for the iMac. I think that's right anyway, not sure how that effects virtual cores either...
