There is a bit of work.Informative, and funny. As long as I uninstall all my ATI drivers, I won't have a problem switching will I? I've only used ATI up until now so I'm more curious than anything else. Even if there are some bumps along the way, I'd like to make the switch for the control panel purposes I explained earlier. Thanks.
Short version:
Driver Sweeper from Guru3D
Download, read and understand the instruction first. Install new cards, boot and follow the instruction.
Explanation:
When the PC is running, there are processes (drivers related program) running which sometimes get left behind after uninstalling the driver. This used to require a bit of safe mode + manual delete files + manual edit in registry to remove it for good, or it will cause performance issue with the new card. Now, there is an easier way given above.
