I just installed this GPU in a Mac Pro 2012 (3.2 GHz Quad-Core Intel Xeon) and it works like a charm

This is a very nice upgrade from my GTX-760

Awesome, for the price, the best upgrade for my aging Mac Pro

Awesome upgrade for my 2012 mac pro tower

I love it, perfect value for your buck

For the price, it was a fair value.

For miners, and from the looks of other reviews, that's who buys these things, I am certain it is a better value than a 1060 6GB.

I am returning it (most graciously accepted by the seller), and purchasing a Metal-capable, Mojave compatible card that has been flashed for MAC.

This board is the best of the "metal" compatibles.

The card ran perfectly with High Sierra; however, despite being a Metal capable card, with Mojave it would never get past the startup screen (the desert scene) and load the Finder (I will spare you describing all of the dialog boxes that would not respond after logging in, and the process symbol spinning for 9 hours, all while the Finder should have been loading)

Price and performance is optimal

So happy prices came back down on these from crazy bitmining phase/fad

Very reasonable price

Other games that stopped working (WOWarships) due to old card no longer supported have extended life

I cannot imagine how loud it is on super-high demanding games

Running assassin's creed odyssey ultra setting in populated areas at 50 fps average plus the freesync working in the background and the game feels smooth

Finally I gave up and re-installed my original Mac Pro display card, everything now works fine using either hard drive

you probably want an NVIDIA card, since those NLEs use OpenGL, and AMD supports OpenCL

During the prior two days the Sapphire Card never missed a beat but after the lock up it never again displayed anything

The Sapphire Card was impressive and worked fine those two days, then in the middle of downloading my new email, everything locked up

It does a good enough job cooling itself

The fans work wonderfully and the card never overheats.

The card os smooth as silk, Final Cut BLAZES, and editing 4k with complex renders and particle effects is now a no brainer.

Apple couldn't explain why it recommended a product that didn't work ...and declined to even check it out

The product looks untouched and the seals weren't broken

The coil whine is insanely loud, loud enough I have to turn up the volume on games

This should go without saying, most GPUs have some sort of coil whine, but again, this is the loudest I've ever heard

I noticed that the more I amped up the settings, the louder the coil whine got

When I ran Steamvr test, the coil whine was equally as loud as when playing on epic settings of Overwatch

I could hear the Western Digital hard drive going through the boot up

Finally I gave up and re-installed my original Mac Pro display card, everything now works fine using either hard drive

‘just in case’; booting from two different hard drives to verify it worked with both old and new Mac OS’s; and planning the conversion to Mojave
