things to do for new build?


I'm not sure how origin works, but steam is not registry bound. So you can just plug that right in - you may have to "verify game cache" on your games so it detects the titles, but you will not have to redownload them. First time installs will also run, but again, trivial.

As for drivers, at the barest possible minimum, you should be getting your LAN driver. Once you have internet access, the rest can often be pulled down automatically.
