Dual RX 480s in Mac Pro 5,1 running MacOS (w/ How-to)

Still works the same way. I updated and ran benchmarks on a R9 Fury X, same speed.
 
Did somebody tested some steam games or pro apps (Photoshop, FCPX, etc etc)?
I've read about benchmarks but I would appreciate some real-life usage comments.

I have no problems in FCPX (apart from NeatVideo, which doesn't support RX4x0 on OSX at the moment).
With an RX480 and an HD5770, BruceX takes 45sec. to finish. With a 750Ti and the HD5770 it would need the double the time.

CIV VI and Modern Warfare III are running just fine.
I didn't test StarCraft II yet, but that should be fine too.

im having trouble updating from 10.12.1, it doesnt show in the updates panel and when i try to download the standalone package and run it it says:

"macOS 10.12.2 Update cant be installed on this disk. This volume does not meet the requirements for this update."

Its a 256gb AHCI Samsung in PCI slot 4

The reason im running Sierra is for the RX480 and wanted to see if there was any improved performance on 10.12.2.

I have tried with and without the RX480 installed and with and without SIP enabled.

Any ideas?

Do you have a supported Mac Pro?
 
Do these look right for an RX 480?

Sorry. Saw this before and forgot to action. How do I get it to you, just add the file here, (it’s 9.8MB)?
It’s from 10.12.2 BTW.

I was messing with trying to get all the CU's and lost all my acceleration. I signed up for the public beta and now with the update I have the unmolested kext.

No problem. That’s b4 right, are the AMD kexts identical to 10.12.2?

I didn't pay close attention but it seems like there was an extra ID in there.

Ok so that is exactly the kind of thing I was hoping to see. That’s on Baffin tho. Weirdly enough I thought the 470 and 480 were Ellesmere.

It is but trying to change that and add the CU's is what lead to the issues with the kext..so I'm not going to play with it right now, I'll just wait and see if a 480 ends up in a Mac.

Happy with that. As soon as 10.12.3 is out I’ll pop my 470 back in.
 
I've just installed an Rx 480 in my 5,1. All seems okay after the 4100 kext edit and the CU script from the r9 thread.

I've noticed during valley benchmark 'Extreme HD' setting, the motion stutters, like a okay for a second, pause, okay, pause...

it's fine on medium settings, all smooth. Is there a reason why it's stuttering rather than moving smoothly, but slowly?

This is my progress from an HD5870

Dual booting/cold booting/sleeping all good?
