Graphics Card Switching Troubleshooting

[Snakeskull7]

Hello everyone,
I currently have a AMD HD Radeon 5670 MSI Graphics card in my Desktop.
And I have a beautiful MSI Twin Frozr GTX 750ti just begging me to put her into my desktop.
I'm all for that Idea but I want to make sure I don't destroy my pride and joy (Desktop) By making a foolish rookie mistake.
How should I go about removing the drivers from my old GPU? Device Manager is the only one that seems to be an option because no drivers are apparent in my "Uninstall a Program" List.

After uninstalling those drivers, should I
- Turn off PC
-Take out GPU
- Put new GPU in
- Install new drivers
- Game on?
or what?

Guru3D - Driver Sweeper

Instructions from page:

Use the official uninstaller(s) of the driver(s) you want to uninstall.
Reboot your PC in Safe Mode.
Run Driver Sweeper and select what to clean.
Analyse lists all the entries possible to remove, cleaning removes the entries selected.
More drivers can be selected for the same cleaning process.

After that, shut your system down, remove old GPU, install new GPU, boot system up, install new drivers. Would be a good idea to download the latest drivers for the card beforehand, since they're usually a decent sized installer. That way you don't have to wait for the download in a limited resolution or anything like that.
