Info on AMD Fusion, copied from the site. The AMD Fusion Utility for Desktops is designed to shut down certain processes, reduce CPU load, improve energy efficiency, and/or increase available RAM to free these resources up for other, more immediate purposes. It can also restore the system to its initial start-up state. The shut-down process can be done with the click of a button. If the AMD OverDrive™ software and ATI Catalyst™ software utilities are installed, they can also be activated simultaneously by the AMD Fusion Utility for Desktops application. Activating a selected profile automatically searches and closes all services and programs listed in the profile that are running at the time of activation. It also starts any hardware tuning options selected. Depending on how the profile is configured, the processes shut down may include network security that may leave the computer system exposed to viruses, worms, and other harmful software. Thus, it is important to be cautious while operating in this state. Stopping an active profile or exiting the application returns the system to its start-up state. Profiles targeting specific processes for automatic shut down can be created quickly, with system processes and hardware acceleration displayed as a list of user-selectable profiles. These profiles can be started and stopped with a single click. When a profile starts, the amount of RAM and CPU power used by system processes decreases, freeing more for other purposes such as gaming. A message with the option to save appears for active applications that implement an automatic saving prior to exit. Processes shut down during a run can be selected by the user. Close requests are sent to each process selected for closure within the profile, and if any process takes more than five seconds to respond, a hard kill command is sent to help ensure its closure. Software for tuning the processor(s), such as the ATI Catalyst™ and AMD OverDrive utilities, can also be activated if installed and configured. Stopping a profile returns the system to its start-up configuration.
