For those with installation problems on the 780G Chipsets; I have recently had some luck with the following installation instructions:
1. Install your Windows 7 Build
2. Install the ATI Windows 7 Beta
Drivers, during the installation choose custom and unselect the "install
drivers" checkbox.
3. Install the new 9.2
drivers and cancel the installation before installation utility starts.
4. Browse to the drivers directory and manually install the 9.2
driver.
CCC from the beta install will control the features on the 9.2
driver, so you're golden.
