Custom installation vs upgrade install

I'm planning on upgrading my vista 64 bit to windows 7 using my upgrade discs i got from HP. I'd like to make a clean installation rather than an upgrade install but there is a warning in the manual that if i choose to custom install, i may need to reinstall drivers that are not included in my discs. What does this mean? Does this mean that if i custom install windows 7, i may need to download programs inorder to run my mouse, keyboard etc? (sorry i'm an no computer techie).

also just in general, is there a big performance difference between custom install and upgrade install?
thank you!

It means that there is a chance that you may not have complete funtionality.
The mouse and keyboard should work but Audio, USB, Video may need Windows 7 drivers in order to get full functionality.

Check HP's web site for Windows 7 drivers for your model. The list should include chipset, network, audio, video, usb and possibly other drivers that should be updated even if the Windows 7 install completes without any problems,
