I am trying to order a 8GB upgrade for my 2.2 MBP today. I have been having trouble finding a definitive answer on a few questions. I know 1600 works but it seems the performance is negligible for the price. When it comes to 1333 is it 10600 or 10666? Can anyone recommend a brand or provide a link? I prefer to order from newegg or the like as I believe crucial will charge my sales tax here in my state =( Greatly appreciated.
