I just ordered components to build a new PC and I'm wondering if anyone has experience using a windows 7 upgrade to do a clean install...I'm planning on getting the windows 7 professional upgrade from microsoft with my student discount (http://www.microsoftstore.com/store/msstore/pd/productID.216644200), but I'm not sure if I should just buy the download ($30) or if I need to (or should) pay for the backup disc as well (+$15). Basically, does anyone know the size of the download and whether it's possible to burn this onto a CD or DVD and use it to perform a clean install, or will I need to buy the backup disc and install off of those?

Note that I have seen the methods of how to clean install using an upgrade here; I'm assuming that this method will apply to me - please correct me if I'm wrong: http://www.winsupersite.com/article/windows-7/clean-install-windows-7-with-upgrade-media
