Things to do before replacing motherboard & proccessor?

[Inazuma]

Hi all,
Tomorrow I will finally be upgrading to an i7 This means I'll also be changing the motherboard.

I heard that you can pretty much just replace the parts and Windows will just be fine, but I was wondering if you lot could chime in on your own experiences and tell me if there's anything I should do other than the usual backing up of important files.

This may be a stupid question, but I suppose after a re-install, programs on my second hardrive will not work either?

Thanks, I got it all up and running now
I'm having a problem of inconsistent hard drive speed though. Using HD Speed, before the upgrade I was getting an average and stable 125 Mb/sec. Now it's 95 Mb/sec and jumps a lot between 60 and 110 Mb/sec. Same goes for my secondary hardrive, although not quite as bad.
