Oh, sorry... my bad. In that case, you're correct and you will need to go to the ATI website and download the relevant driver. You can, as you correctly pointed out, do this beforehand if you wish and then simply run it from CD. It won't make any difference but might be more convenient as it will be quicker (and you might be like me always wanting to do things as quickly as possible once the PC is up and running
)
As for the ethernet card... you can do it before or after. One thing you might want to consider is if you want to download a firewall such as Zone Alarm, and the latest service pack for your version of Windows, and install these from CD instead of downloading them once your PC is built. Then you can install these quickly, which means your PC will be vulnerable to attacks for a far shorter period of time. Just an idea
