That could change on new AMD cards, but we should wait and see (talking about flashing for bootscreen support)

That is a real bummer since i've bought GTX680 to finish a few jobs and wait for price drop on RX580s.
Actually, i was very satisfied with R9 280X i had in cMP, but it started switching off both of my screens when under any type of load (gave it to a friend and he is using it without any problems in Windows with older drivers).
I've bought GTX980 afterwards, since all AMD Tahiti GPU's are quite old, run hot and most of them were mining for a few years, but it gave me horrible performance in FCPX - it wasn't being used at all (*was great in Premiere Pro and all the games).
So i've decided to give a chance to GTX680 and it's a real surprise in cMP still. Although it si much slower than GTX980 in BruceX test it works much better in "real" usage in FCPX. Who would guess.
I was hoping that introduction of Radeon Pro 580 in this years iMac will mean that we have new king in town, but it seems that we have to wait for High Sierra to see some real improvement with this GPU...
Are these results in a cMP ?
I've been trying to get some "good" performance from my cMP 5,1 with twin 580's but I can't seem to get them working really good. 22 sec BruceX was with 1 580, the added a second but Bruce took longer, up to 29 sec. Then removed a one 580 and now its even worse.
Tried different Sierras, 10.12.5 and 10.12.6 and also High Sierra, but It just dosn't seem to work very good.
Or maybee Im doing something wrong or Im lacking information.

12s sounds very reasonable to me indeed. I do not own this card (yet), however, my dual 7950 setup can do 15s. Since the 480'is a bit more stronger (already consider the driver performance, it still stronger than the 7950). 12s is right at the expected range.
Thats really odd. The rx 480 and 580 are pretty much the same card. I wonder if the drivers are causing the issues but I dont see how.Are these results in a cMP ?

Can anyone please confirm 67FF in the 10.12.6 kexts? I'd love to carelessly update without patching.

How are you powering these two RX 580. As far as I know, no RX 580 uses a single 6-pin plug.
Also to keep in mind other components of your Mac Pro may slow things down rather than the GPU.
You'll have to rephrase your question, or provide a bit more detail, as it makes little sense I'm afraid.

Like im planning to get 1080 gtx or 70 so would that work on 5,1.
I still don't get it?
All new cards are 3.0, some are 3.0 x8 (rx560 afaik). Mac Pro has PCI-e 2.0, but all AMD cards are running at 1.1 speeds without mod. Nvidia drivers are enabling 2.0 speeds in osx with unflashed GTX cards.
But I still don't understand what your question was...

Unless you're going to use that 1080/70 in Windows/BootCamp only then I'd think twice.
I had a 1070 in my cMP and ditched it. It was a buggy mess. Pascal drivers in macOS are not worth using.
Get a Sapphire RX 580 Pulse 8GB instead and you'll be MUCH happier with it.
I do have a 1080 in my other cMP on which I run Windows 10 exclusively and it works great!
Just don't buy a 1080/70 to use in macOS. You'd regret it I think.
Also, the big disappointment for me was that FCPX is using CPU in many tasks when Maxwell or Pascal WebDriver is seen by OS. So, slow as hell...
I am back to GTX680 and R9 280X swapping until 580's become available.
No, as long as you are running macOS Sierra 10.12.6 or the High Sierra beta then the Sapphire RX 580 Pulse 8GB is plug and play.

Ha! Exactly what I did, the GTX 680 is back in my cMP and all the issues disappeared instantly.
I've had the Sapphire RX 580 card on pre-order for almost 2 months now!
I bought two 6pin to 8-pin adapters and took the power from the two nearest outlets, just next to the GPU's.
My 580s however aren't from the Sapphire brand but from Asus. Could this matter?
I haven't done anything with the drivers, I've read the 580s should have native support? But maybee I need to look into the whole Kext-subjet?
It's a 2009 but flashed to 5,1.
[doublepost=1502919578][/doublepost]
I think so to.
But when reading other threads I notice there is alot of talk about the Sapphire 580's, mine are Asus, but should that really matter?
Perhaps I've misunderstood here, but are you driving each 580 with a single mini 6 pin to 8 pin adapter?
Surely you should be using a dual mini 6 pin to 8 pin adapter for one card, and then be powering the second card through other means.
As I said, I may have misunderstood what you stated however. Please correct me if I'm wrong.
Looking at the picture that was posted it does look like they used a 6-pin to 8-pin adapter, not a dual 6-pin to 8-pin adapter. There is only one feed going to the video card. The card must be drawing all it can from the single source and is able to boot, but when it is put under a load it is underperforming because it is underpowered.
I have a MSI Radeon Rx 580 Armor 8G OC installed and I used a dual 6-pin to 8-pin adapter and I have had no problems with this card. All Radeon Rx 580 should work ok as long as you properly power it fully.
The card from ASUS is not a problem. However, you connect a 8pin to a single 6pin is the problem. You should not do that on a cMP.
The correct cable to be used is the dual mini 6pin -> single 8pin.
