Configuration:

Catalyst Control Panel:

Once all your drivers are installed and you have rebooted your computer, you might want to configure the Catalyst Control Panel so you can change the settings to your liking. Here are just a few screen shots of the ATI CCC.


 


 

 

 


There is no difference between this and previous versions. As you can see, there is no ATI Overdrive option. Since I do not have the eight pin connector, the overclocking tool was not installed.
