Mojave 10.14 on cMP

[lowrider]

Hi community
I have a MacPRO 5,1 with:
-  ATI Radeon HD 4870 512MB
-  NVIDIA NVS 510 2047 Mo
the firmware version are MP51.0089.B00

at the upgrade to Mojave the Mac Pro still crashes at system loading before the login

I removed the ATI card and the computer starts without worry.
only since the NVS is not EFI.
I do not see the boot loading and I can't which another boot volumes

i have see this articles:
Install macOS 10.14 Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012) - Apple Support

i will know if the ATI Radeon HD 4870 512MB is compatible with METAL

I have see some rumour about 10.14.1 will change a little bit my problem.
Can someone tell me if I need to change my graphics card or not

In a word - Yes!  Your card is NOT metal compatible!

yeah, gotta be 7xxx or later AMD

funny  thing is Apple keeps giving the nvidia folks the heave-ho, yet much older nvidia cards have metal support

I have both a Nvidia GTX 780 and a Radeon 7970.  Since the release of Mojave, the 7970 blows the GTX 780 away with the few games I have played.  Borderlands 2 is on average 5 to 10 frames faster.  Fortnite (a Metal rendered game from what I've read) works flawlessly on the 7970, while it stutters like crazy and is pretty much unplayable with the GTX 780.  I'm under the impression that even if Nvidia were to get their web driver working again, performance may still suffer greatly.

yes, Apple has bent over backwards trying to keep their choice of AMD from looking as stupid as it was.

they have hamstrung Nvidia ever since
