Hi My dad is going to change his MBP 15.4 inch 2.2 Gh Core 2 Duo/2Gb RAM from 2007 (December) with the new MBP 2.4 Quad Core i7 currently available. He asks the crucial question: "How much faster is it crunching video editing ?" I said: " A lot..." So, can anyone help me quantify that answer ? Thanks. stj.
