Want to make sure Windows 7 Upgrade Will Work Before I Open Disk

I had an upgrade take almost 8 hours during the RC timeframe, on a fairly new machine (quad core Q9650, 8GB RAM), and I've seen some take upwards of 15 hours on similar hardware. The more you have installed and/or stored in your profile on the volume you're installing Windows to, the longer it will take. Saying it won't simply because you've never had a long upgrade doesn't make it fact.

I've had an upgrade from Vista to 7, on a modern PC, take well over 6 hrs. It might have been longer, as I got sick of waiting and went to bed.

I'm convinced and will be doing a full install of Windows 7 over Christmas. Thanks for all of the advice!
