i would suggest an early backup to your software install. such as after window7 is fully updated and activated with your chipset driver, device drivers, video drivers and security suite installed.
get some verbatim data life plus dvd at micro-center and make a master backup. you might just fit the above on a single dual layer disk using the image creation tool in windows 7.
personally, imo, the software on the asus support dvd outside the hardware drivers is junk. just don't use the install-all option, save the asus utilities for the end, or another day.
