    Can I upgrade my iMac?
    Is it possible to upgrade the memory from 8gb to 16gb, and video card from AMD 4850 to the latest version on my 2009/10 iMac? Running Snow Leopard and using boot camp for games on windows (COD etc) but some new game requirements (COD Ghosts) exceed my system ability. All advice appreciated.

    Does this apply to you?
    iMac Intel 27" EMC 2309 or 2374 Graphics Card Replacement - iFixit

    PS - I don't have an iMac, but typically, Mac graphics cards require Mac-specific firmware. Don't try to use a non-Mac card (cheaper) unless someone confirms it will work.

    As for RAM, that may depend on exact model of iMac, too. What model is yours?

    Depends on the model iMac you have. Some models from 2009 only support 8 gb memory. Late 2009 models support up to 32 gb ram. Check here to see what your iMac supports Apple iMac Specs (All iMac Tech Specs) @

    You have a late 2009 27" iMac which uses the AMD 4850 card. Your iMac can be upgraded to 32 GB of memory. As for the graphics card, I don't know if on that particular model the GPU is on a removable card or whether it's surface mounted to the logic board. You'll need to check with to see if it's removable. And if it is, you need to do some searching to see it can be replaced with something more powerful. As to replacing it with the latest version of GPU used in current iMacs, the answer to that is no.
