    Consider that sometime in the near future while my iMac is still under warranty I'm intending to upgrade the 5200 rpm hdd to a 7200 rpm hdd.

    Snow Leopard being a 64 bit os and to get the full benefit from it requires a 64 bit video card and core 2 duo I was wondering if it is at all possible to swap out or upgrade or replace the 32 bit video card in my 2008 core 2 duo with a 64 bit video card ?

    There is no such thing as a 64 bit video card. Snow Leopard does not require one. And you can't swap GPUs.

    Is your iMac white or aluminum? I thought all aluminum models came with 7200rpm HDDs? Also, I don't believe you can change the cards because they are soldered to the board like the macbook pro's. I could be wrong,, which I am alot now a days. ;)

    There is no such thing as a 64-bit video card. You cannot change cards.

    This is what it says in the system profiler

    It means that each pixel has 32 bits of colour data. This is nothing like a 64 bit CPU. The 32 bits are generally 8 bits each for red, green and blue and 8 bits of padding (these are alpha bits but at a screen-buffer level this makes no sense). It has nothing to do with the max addressable ram of the GPU which is what makes a CPU 32/64 bit.

    In short just ignore it.
