Hi Guys. I have a late 2009 iMac and wanted to speed it up. It's getting to the point now where programs are starting to run slow, and games like Football Manager are slowing down and not running as well as they could. My iMac is the following: 21.5-inch, Late 2009 (Mac OS X 10.7.4) 3.06 GHz Intel Core-2-Duo 4GB 1067 MHz DDR3 ATI Radeon HD 4670 256MB I see there's space for another two RAM chips, which must be 1067 cards. Would it be as simple as purchasing another couple of 2GB chips and putting them in, or are there other things I can do to improve this once great machine. Or, should I bite the bullet and buy a new Mac? If so, what do you think I could get for this one if I sold it. Perfect condition. Thanks for your help.
