I worked my way from 13.8 and each one made the whole system edgy. 14.4 was somewhat stable but with 14.9 just bringing the CCC suite window up on your desktop and closing it would cause CCC to crash. Post crash,(stated in windows error report as an appcrash), the entire system would crash or reboot.
Come to think of it, AMD need to revise their driver packages and suites. There's just one or maybe 2 driver packs for their entire lineup of chipsets, raid/sata, GPU's and APU. Uninstalling them is a PITA as you either need to manually select the drivers to uninstall (via CCC uninstall window) or you risk uninstalling everything with "express".
This is the main cause for the drivers either not installing properly(with an error/fail report at the end of installation) or you have a tough time with Drive sweeper. Worst case scenario, a full format to clean the crud off the system due to broken registry entries.
