The ATI cd has:
1. drivers-not so important given that you can download the latest build anyway
2. DirectX6-since most everyone has 7 or 8, this isn't important
3. WDM inf files-not sure what these are for, but I was told that they are related to the...
4. ...capture components
5. ATI multimedia center-definately important if you want ATI's DVD player, VCD player, etc.
6. ATI Gart drivers-definately DON'T want these
