Mac Pro 2009, I need a Metal supported GPU, 680 or 780?

Ah, of course I could pop in an old drive as the temp OS, and clean install to my SSD, didn’t think of that.

But still though, not quite sure I understand why I can’t start from the USB technically. Is it pretty much just because the installer doesn’t recognize my Mac as a compatible system because 2010 didn’t exist with 680?

This only occurs with GTX-680, AFAIK. Apple USB installer seems to have a bug with metal detection with this specific GPU.

Oooooh, hahaha. I get it. Sorry for my ignorance.

I absolutely had no idea why this wouldn’t work. But I got like 4 empty drives now, I’m setting everything up from scratch and wanted to start fresh with Mojave. I’ll install 10.13 on drive 2 and use that to install 10.14 on drive 1, if I understood you correctly?
Then I would go through a typical clean setup procedure, and wipe drive 2 afterwards?
