The QX9300 is easily the best of the 4 listed. However, I imagine it's much more expensive. does your notebook's mobo support all of them?
I am in the process of purchasing a new laptop to work with my video editing which I will use for customer's work. Well I am just trying to decide if I then cannot afford the QX9300, then in what order are these cpu's placed from best to least. Please help! and Thanks.
