My iMac is really sluggish lately so I plan to upgrade the HD to 2TB and do a fresh install. I also wanted to upgrade the RAM but I wasn't sure if I should install the 3GB or 4GB. I know it takes maximum 3.3GB or something like that, but I heard that installing 2x2GB will take advantage of dual channelling and give it a bit more of a speed boast. I plan to buy OWC branded RAM, and the difference between the two configurations is only like $20, but hey, money is money. Any suggestions?
