I upgraded all my systems. From a 1 GB RAM 10"netbook to my latest powerhorse. All went nice if you leave it alone the first week or so. NO CLUE what they all do in that first week after an upgrade, but it likes to be left alone for a week or so. After that, reboot, and you have a nice system. (Some reboot automatically a few times, and you need to log-in again, but after that? leave it alone. Your turn is AFTER the first week has gone by.
