Too early to tell until we see what GPUs Apple starts including in its computers.
For example 5770/5870 were not supported in Snow Leopard when it was released (10.6.0), but support was added later in 10.6.4 when a Mac Pro was released that included those cards.

I've been running a pair of RX 480 GPUs since DP2 to the latest GM build 16A323. While there were small revisions, the way in which the RX 480 behaves in macOS 10.12 Sierra has not changed (OpenCL works but OpenGL doesn't).
The RX 470 GPU which I also have been testing with macOS is working very well - that has not changed from DP2 to GM 16A323 either.
I don't have Adobe Premiere to test. I tried the Bruce X test with the dual RX 480. The average is about 11 seconds.
the rx 470 is only about 10% slower and works so will be a much safer bet for pro apps.
but there is the possibility that you can run a rx 470 for display + rx 480 for compute but vary few apps are dual gpu aware and it may give problems so something more like dual rx 470 may run more stable, or the nano.
what version of Adobe Premiere are you using?
you may hit problems like GTX 9xx users have with random crashes in adobe apps so might be more safe to wait and see how things progress ^^
im hoping to pick up one for use with adobe CS6 and video work 4-8gb vram for the win
not that i work at 4K at the mo

Not to be a loon, but why would this single fan card be better than say, this guy?

(Dig the crazy HTML 5 animation.. "military class components.." does that mean it could withstand an EMP pulse?)
I see lots of space for the air to get in and two big honking fans, does having the board closed off with a single fan controlling the flow make it any better?
Objectively, the fans over heatsink design is better for overall cooling for the card. We're working with a tower Mac Pro and the more hot air pushed outside the case, the better. That's why most Apple GPUs are blower style with one fan blowing heat from heatsink out the back.
I see.. so the MSI is actually worse for the cMP because it's not taking the heat out of the system per se, just recirculating what's already trapped inside to cool the circuits. It would be better in a PC running in an open case then.
RX480 Pulse Check in MacOS Sierra - GM2.......
Luxmark 3.1 is slower than a 7950 from too many years ago.
RX 480 @11575 vs 7950 @11866
Open GL is better. A majority of OpenGL calls function and renders properly until double buffered shader modifiers are applied to a surface. At this point, the AMDRadeonX4000GLDriver takes a face plant..
The main thread of the App hangs, along with the OS. After a wait, the application eventually crashes after the x4000GLDiver realizes it's shorts are soiled and cleans up the mess. Which is better than the hard-crash and MacOS lockup that used to occur.
Overall. Somewhat functional, not complete, and disappointing OpenCL performance.

I have no problem running the RX460 inside the Akitio attached to my PC. it is probably power management the issue with the Mac.
Heat can't stay and build up in there, even if it was sealed up. What you mean to say is that heat isn't moving out as fast as we would like it to because of the design. Yes, that little compartment in the middle of the cMP case isn't very good for circulation even with the fans and cheese grate.
if you say have only 1 gpu then having a blower may not matter so much but with setups with multiple pci cards heat not being pushed out can be more of a problem.
if you have 1 pci card a dual fan card may work better for you kind of depends on how you feel & the macpro was designed for blower cards so all the hot air from the gpu is pushed out instead of re-circulating

I personally like the cleaner look of blower GPU. Most reference cooler from Nvidia and AMD are built this way.
blower coolers tend to keep heat out of the computer better but the card tends to run hotter (inside the card which is fine) and the fans can make more noise when working hard also when a new card comes out the first models for sale tend to be blowers. (and sometimes they take up less space)
2-3 fan cooler cards tend to run a lot cooler and with less nose (there for boost better/higher & overclock better) but it also means the heat is not being moved out of your computer, if you only have 1 pci card this is not so much of a problem but if you have 2-4 hot cards next to each other in a case this can turn in to a problem as they are using hot air from say the card above to cool the card below etc..
but im tempted to say as these cards run with only 1-6 pin the heat they put out will be a lot less than cards with dual 6 pin etc
theitsage, im not a fan of all blower cards (or most card's with 'gamer' looks aka ugly as hell) but that Sapphire looks nice the silver dots remind me of my cheese grater macpro
