Hey All. I have a mid 2007 17" MBP - 2.6 GHz - 2 GB 667 MHz DDR2. Looking to upgrade the ram to 4GB, and just a couple of questions. - Any preferred brand? (Kingston, etc) - Will I be able to sell my 2 GB ? (any market for it, or just keep it, etc) - I live in Ontario Canada, so any vendor recommendations appreciated. Thanks in advance.
