RTX Series Cards have Native Bootscreen Support!

A YouTube channel "Linus Tech Tips" had a video that showed how to use a cheap GTX 1060 crypto-mining card with no video output on the card itself. What they succeeded in doing was to use the on board Intel graphics video port to output a video signal from the GTX 1060 card.
Sorry, I'm failing to see how this is in any way relevant to Mac Pros. Care to explain?
Nehalem and Westmere Xeons don't have onboard video, most Xeons don't have it btw.
There may be something here that might be related to how the Apple EFI Kepler's are behaving with the Pulse dropped next to it?
I have observed Compressor using my RX580 during rendering when using both GPU's in macOS but displayed via my 770's DP, but haven't been able to test much more extensively without triggering shutdowns; I don't have a secondary PSU at the moment.
I can replicate the exact setting's in Windows using the RX580 to render using the 770's DP (in certain titles), thanks to Afterburner's ability to limit power draws-but I still trigger shutdowns under heavy load.
I need Pixlas or secondary PSU, I know-I'm testing a theory and it's working great IMO beyond needing more power.

I believe the Apple Kepler's are acting as their "native" VGA output, similar to a Integrated Chipset. The programing language is already there-they would simply have to bin the dataset in the direction to apply it that way, correct?

You are seeing a compute card, not the display being sent from one to another, this is a very different thing.
Agreed, but I'm hoping that they are just getting started-and there may be more to come. I need to figure out power first before I get to fully test it. I'm hopeful, to say the very least.
Your are confusing things. Mac Pro don't have a GMUX controller to route the GPU output from one GPU to the other like MacBook Pros with dedicated GPU and integrated GPUs have. It will never work as you want without a GMUX.
Even with GPUs prepared for that, like some new eGPUs, somethings don't work or work poorly. See the eGPUs with RX 560.

Anyone that did testing on these RTX's, was pairing them with a Mojave approved AMD/NVIDIA chipset attempted in any OS?
I didn't read any attempts beyond single GPU use within the thread, and I've achieved a flashed 770/580 combo behaving moderately well together.

I understand-but they do display. I'm not necessarily looking to "use" the RTX in Mojave, just seeing if it can boot and recognize the AMD compute engine; and what behaviors it exhibits.
I already have Mojave use covered, worst case I need to pull or swap a GPU for creative workflows in macOS.

You should buy one and test it, since you are betting that it’s going to work.
I already showed that it’s not going to. It’s like VMware Fusion before the drivers are installed.
So in theory, the same build used for the GTX drivers that work in High Sierra should translate for the new cards? Why hasn’t anyone been able to crack it independently looking at the old code?
I don't understand your question. What "old code" are people supposed to look at exactly?
I still don't understand your question. Firmware has nothing to do with the lack of OS drivers for these GPUs. What exactly are you proposing someone does?
I read all the rtx threads and tried my own experiment. Coming from a flashed 1080ti. Mac Pro 5,1. High Sierra and win 10 on separate boot drives. Boot runner also. Zotac rtx 2070. Dual mini 6 pin power to single 8 pin cable.
On boot I get the apple boot screen. I get boot runner. I can boot to windows and have latest Nvidia driver so all good. Can boot to OS X and get no graphics acceleration of course because no rtx driver. The driver I have installed is latest for high Sierra.

Thanks for one more testing on this and posting your (not unexpected) results! At least another confirmation for the bootscreen!
I'm very interested in this card too, but, unlike many others, have not giving up hope on the drivers. Why in the world should NV have developed this stuff for over seven years with Apple not even selling one single computer beeing able to use NV cards an then completely stop these activities as soon as there, after all this time, a modular upgradeable Mac reappears on the scene?

Why are all of you so sure about that?
...and why, in the first place, should NV finaly implement Mac-bootscreen capabilities to the RTX-cards not wanting them to ever run in Macs? The 7,1 is not even out yet. And i strongly doubt that there will be only one breed of GPUs for those machines for their whole lifespan.
So many things estimated "dead" since there are Macs, which happily came back to life not even half a year later. We will see...
