Specs: iMac (27-inch, Mid 2011), 3.4 GHz Intel Core i7, 16 GB 1333 MHz DDR3, AMD Radeon HD 6970M 2048 MB I read that it was possible to upgrade the older iMacs to 32GB with the latest Mac OS X. Is this true? If I can, will the extra RAM be beneficial? I don't do video editing or anything similar to that. I just use a lot of media at once [gaming, music, videos, etc.]. The prices for the crucial upgrades are fairly reasonable, so it wouldn't break the bank for the performance enhancement if this would even occur. Furthermore, are there any other beneficial upgrades I could perform on this computer? Thank you in advance for the help!
