Hi, I'm trying to decide which one of the following is a better upgrade option for me. I have the launch unibody 2.4ghz, 2gb ram macbook pro. I'm thinking about either upgrading from 2GB to 5GB of ram (1+4) or 2gb to 4 gb of ram (2+2). Here are the links to newegg. 5GB Option: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231265 4GB Option: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231213 Thanks!
