I wanted to post this as a warning to maybe save those running win8 with AMD hardware some future headaches. AMD released their latest Beta driver pack today -- a leaked copy is up on guru3d.com. Posts in the thread for this driverset include reports that it won't install in win8, that win8 may be missing from the configuration files. Right now the official [non-leaked] drivers are not up on AMD's site -- I have no idea if they'll be different.
Some people did a lot of work trying to get the new driverset installed before it was reported that it does not include win8. So if you're running win8, in the future you probably want to check 1st to see if win8 is supported before you do too much work adding new drivers.
