Updated HD4000 to Asus GTX960; stuck at apple logo

[Fokke]

I want to upgrade my graphics, so i bought a Asus Strix GTX 960.

I have a running Hack with Sierra 10.12.2, more info in my profile.

I updated to the latest clover; 3961

I downloaded the Nvdia web drivers;
NVIDIA Alternate Graphics Drivers for macOS 10.12.2 (16C68)
https://images.nvidia.com/mac/pkg/367/WebDriver-367.15.10.25f02.pkg
and ran this installer.

i edited my config plist:

Code (Text):
<key>SystemParameters</key>
<dict>
<key>InjectKexts</key>
<string>YES</string>
<key>InjectSystemID</key>
<true/>
<key>NvidiaWeb</key>
<true/>
</dict>

Rebooted. All still working.

Then i installed the GTX960card in a pci slot.

Clover starts, and then the Apple logo appears. The progress bar is ok, then slow, then very slow and finally stalls, and i have a black screen.

Where do i go wrong? what to do to solve it?

I have a MacBookPro on which i can do edits to the EFI and plist or whatever.

Do i need to select Inject Intel (for the HD4000) although no display is connected?
