Bought new HDD, what do I need to backup off my old one for Windows reinstall?

[broona]

I've ordered a 320gb Seagate 7200.10 drive which will be replacing an old 80gb Western Digital Caviar IDE as my boot drive, what do I need to backup on my current installation to ensure a smooth reinstall on my new setup? Thanks in advance.

no need to reinstall

acronis trueimage or ghost will transfer everything to new hard drive

Thanks, but really looking to reinstall, got so much ***p on currently that it's got to be a good idea! If it's gonna be too awkward to backup and start afresh, will give one of those utilities a go, cheers.

I'd like to keep my emails/contacts/profiles from Thunderbird, my favourites/profiles from Firefox, My Documents (obviously!), anything else that would be handy!
