After constantly finding myself low on ram, I just placed my order for the 16GB kit from Crucial. I hate to have to open her back up and risk stripping the screws, but I need the extra ram. Xcode has been eating crazy amounts of ram. With only a few apps open, i have only 117mb of my 8GB free. Mad i didn't buy this ram last night, to apply the amount to the coming tax preparation. My next move is a SSD, and move my current drive to the DVD/CD bay.
