One thing though, Given that most XP users are running 32-bit, your best best in upgrading is to move to 64-bit as there are cases where Calibre does need to be 64-bit and if you stay with 32-bit, you will still be ram limited to 3GB.

Moving from 32-bit to 64-bit means starting over. So backup all the data from XP that you need/want to keep and then do the install. You will have to reinstall all of your software so find the install files or CDs/DVDs. If some of your installs is from downloaded software and there is a 64-bit version you will want that.
