Restore Points in Windows allow you to create a quasi "point in time" snapshot of the computer's current state. It's not for files. Rather, it's for any time you install a new program, driver, Windows update, etc.

Using System Restore to create a Restore Point before you use AMD's utility will achieve what you need.

• Create Restore Point.
• Power off computer and replace the GPU.
• Use computer and test new card.
• Once done, power off computer and replace the GPU with the one you're keeping.
• Use System Restore to recover to the prior Restore Point.

I'd argue that Display Driver Uninstaller is potentially faster than using System Restore. But I haven't used System Restore since the Windows 7 days and it was really slow back then (also was using HDDs, too). System Restore is probably just as effective now.
