Hey all! I bought my iMac in Aug 2010, and when I run the System Profiler, it says my system is a Quad Core i7. I am wanting to upgrade my RAM to an additional 16Gb (on top of the 4Gb that's in there now). So when I go to Crucial site (as well as other sites), it says that the Quad Core i7 was mid 2011. But I've had this for 2 years. Is that possible? Can the System Profiler be wrong? I did buy a refurbished Mac, but it was only a month old when I bought it. Any help would be appreciated. Thanks!
