I had a RX 560 (see my previous post) 'GIGABYTE RADEON RX 560 Gaming OC 4G' Rev.2. It did not work correctly on my cMP early 2009 flashed to 5.1, on 10.13.3; I had a couple of screen flickers while others did not have these kinds of problems. The RX560 is not recognized natively by OSX on 10.12.6 and really noisy compared to the RX580.
Click to expand.Apple identifies the card by the product ID, if the driver found a different product ID, the generic framebuffer is used. I don't know how this works with the RX 560, but with RX 580, if the driver find the product ID for Sapphire Radeon Pulse, the Orinoco framebuffer is attributed to the GPU.
This is important because some of the cards have non standard ports layout than the models that Apple supports and recommend. People are finding that some non reference RX 580, like Gigabyte Aorus, are practically incompatible with Macs. May be a bad card, but be warned. Click to expand.Usually no need to get the exact model. However, the more deviate from the recommended model, the higher the chance has compatibility issues. HD7950 Mac Edition card is a reference card made by Sapphire. Most (if not all) Sapphire 7xxx card can work on the cMP.
Most (if not all) reference 7xxx can work on the cMP. All 7950 reference card 100% can work on cMP. All 7970 reference card 100% can work on cMP.
However, some customised XFX 7950 can NOT work on cMP. Or like RX460 (which has same device ID as the RX560), but AFAIK, all single slot RX460 won't work on cMP (the Apple recommended MSI RX560 4GB model is a dual slot card) Therefore, if possible, get this one. Click to expand.Not all RX-560 are equal. Some require more power than others (nearly twice as much) and an aux power cable, which is not a big deal. But it is convenient to be able to just plug in the card and go without fiddling around with a power cable, especially if you plan on removing and reinstalling the card very often. Or if you ever plan to install a 2nd card, even temporarily, which needs aux power from both of the available aux connectors.

And it's always nice to have a card that requires less power, no cable, runs virtually silently, etc, especially if you ever decided to use 2 RX-560 cards (for more than 3 monitors). The MSI RX-560 ITX 4 GB card (the one officially supported by Apple) is such a card, and it's cheap (I paid $130 for a new one.) The RX-560's also come in two basic performance models, one with 14 CUs/896 Stream Processors and one with 16 CU's/1024 Stream Processors.
The MSI card is the 16/1024 version. The performance difference is pretty small, but again why not use the Apple approved card just so you know it will be supported for a while? Click to expand.There are, or were (not sure which of them are still available new), numerous versions of the Sapphire Pulse RX-560. They fall into both categories I discussed above, so people considering them should check out which version they are getting - if it matters to them. Again, to most people it probably won't matter if it requires an aux power cable or not, whether it's a 45 watt, 60 watt, 75 watt, or 90 watt card since they are all very low for Mac video cards, and the difference is less than 15% whether it is a 16 cu or 14 cu card. There are also slightly different clock rates for different cards, but those differences are slight. But if you do care, then look carefully at the specs for the Sapphire card you are considering.
This is the only officially Apple supported RX-560 card (Apple calls it the MSI Gaming Card): MSI RX-560 AERO ITX 4G OC 16 CU/60W/no aux power cable supports 3 displays (DP/HDMI/DVI-D) This is apparently a new card? It's not exactly accurate to state that the MSI RX 560 is the only officially supported RX 560. It's just the only one they specifically mention as being compatible that they have tested. It hasn't been given any special frame-buffer or identification in the drivers that would make it better supported than any other RX 560 that has a correct device ID. They state that other RX 560s are also compatible, but don't specifically list which models are. Instead they state, 'Third-party graphics cards vary, so you should check with the vendor of your specific graphics card for compatibility details.' It's not exactly accurate to state that the MSI RX 560 is the only officially supported RX 560.
