Change of Hardware?

So I just got myself a GTX 980 Ti to replace my R9 390X and I am not sure about the installation procedure.

Currently I am using El Capitan and Clover loads a VBios for my XFX R9 390X. How do I go about installing the NVidia card? I am presuming the following:

1. Open Clover Configurator, Mount EFI and open config.plist
2. Remove the Load VBios
3. Shutdown
4. Install new NVidia Card
5. Restart with ... (some boot option?)
6. Install NVidia Web Driver (where can I find these?)

Or...
