Use AMD because you can update your drivers WITHOUT the fluff that Nvidia makes you use. Just follow instructions and the option is there: Driver only!
For example, using the Nvidia video card, right click on your desktop and see what you get? Is the Nvidia Program linked? You don’t want a video card program running in the background. Again, too much fluff. On my PC running an AMD card a right click sends me to Windows Display settings, not an AMD program.
Lastly, open your Device Manager and look at your ‘Sound, video and game controllers’. All you want to have operating here is your sound card interface, (and hopefully you have a quality external sound interface). You do not want any VIDEO RELATED card ‘High Definition Audio Device’ or ‘Streaming Audio Device’. Disable these. This would also include the MB Audio card.
On my PC for example, I have 5 devices listed, only two are external audio interfaces - these are not disabled - the other 3 are
1),AMD HD Audio Device
2) AMD Streaming Audio Device
3) Realtek(R) Audio
and they are all disabled.
