I have an early 2009 Mac Mini which currently has 4GB (2x2GB) of system memory which I upgraded myself when I first bought it. Now, 3 years later, the system does tend to get a little sluggish at times and I am thinking to upgrade it to 8GB (2x4GB). I see OWC offers an 8GB memory kit for it here for $50. I am just curious to know from others with 2009 era Mac Minis if they found great performance improvements (provided you have the necessary EFI updated)? Appreciate any feedback. *Note: I was planning to purchase the 2012 Mac Mini but need to hold off for a year or two so I am wondering if this will tide me over. Thanks.
