I've never updated via CD. Jacksmith's suggestion is good, provided you have broadband. If for some reason it's a pain in the rear to it that way, I'd suggest you hold off for 2 weeks. The next update is rumored for the first week of December. At least that way you'll be current until late spring. While you're at it, you may want to boot up your games to grab any updates, and get any downloadable content you might want.
