upgrade 2012 macbook pro graphics card to support mojave

Then there this card the Sapphire PULSE Radeon RX 580 8GB GDDR5 on Newegg for $179, which is a really good deal for making it possible to ugrade to Mojave: Then there's this card the AMD Radeon Pro WX9100 for about $1500 that should definitely support metal: Also I don't know if the Nvidia Quadro is compatable with Metal because Apple doesn't mention it in their knowledge base about Metal Support for Mac OS X Mojave, but this card might support the thunderbolt card from HP if the thunderbolt card from HP supports Mac in order to add thunderbolt support to my Mac Pro 2012: The same goes for the Nvidia Quadro K4000 in the link below too as with the Quadro K5000 considering I don't how it supports metal and I don't if it's also compatible with the thunderbolt card from HP that I also want to get to add thunderbolt 2.0 support to my Mac Pro 2012 because I don't if the Mac Pro 2012 supports the HP Thunderbolt 2.0 card and I don't know if it will work with the Quadro K4000 officially for Mac either.

Here's the Nvidia Quadro K5000 for $599 used on Newegg, but I don't how it supports metal and I don't if it's also compatible with the thunderbolt card from HP that I also want to get to add thunderbolt 2.0 support to my Mac Pro 2012 because I don't if the Mac Pro 2012 supports the HP Thunderbolt 2.0 card and I don't know if it will work with the Quadro K5000 officially for Mac either: Here is the Sapphire Radeon 7970 HD officially for Mac with 3 GB of video ram on Newegg, but it's out of stock now: Here is the same Radeon Pro WX7100 from dells website for $399: This is the Radeon Pro WX7100 that has 8GB of video ram and is single din on Newegg for $499:

I need help deciding which video card to get for my Mac Pro 2012, so that my Mac Pro 2012 will be able to support the Metal Graphics API to allow it to upgrade to Mojave.
