Finally decided to pick it up and do a little upgrading on my Core Duo MBP. I picked up a 320GB hardrive and more RAM, bringing me to 4GB total. Here's my dilemma: Do I throw in the new drive and install Leopard fresh? Won't be too hard to put programs back on as I don't have a whole lot. OR Do I do a backup and put it all back on as is and upgrade? Or is that even possible with OSX? One more thing. I currently use Boot Camp with Windows XP Pro. Since I am going with 4GB of RAM and XP won't recognize it, is there a 64 bit Windows that I can use? I like to have a Windows partition available for a few apps that I am used to working with and maybe a game or two. Nothing major of course.
