    It is clear from the chatter on several Apple-related forums that the Aperture software takes advantage of the GPU, not the CPU.

    If that is true, when I buy a new iMac, should I pay the extra $200 to get the 780m GPU with 4mb of video RAM?
    Or will the 775m GPU with 2Mb of video RAM do an adequte job?

    The most intensive application of the computer will be Apple Aperture.

    Well if you can afford it, go for the 4GB of GTX 780. You're going to need it a few years down the road when apps become increasingly GPU-intensive.

    If you intend to change iMacs every 2-3 years, go for the 2GB GTX 775M.

    The 775m will do more than an adequate job. There is less than a 10% performance difference between the 2.

    That's not true at all. The difference is closer to 20 - 25%, depending on the application.

    Aperture, however, will be *more* than fine with the 775M. Even the 755M would be acceptable, or the Iris Pro: it's not a GPU heavy application.
