    Hey guys I am in the process of upgrading the graphics card of my flashed Mac Pro 4,1. I use Final Cut Pro X daily (work). I’ve heard good things about the XFX version of the card as it appears to be stable enough for higher work loads. Is this true? What do you guys recommend?

    I use a sapphire one (think its 4gb though) - I've heard x after 480 is a bad thing?

    Anyway, the one is this video is great for fcpx

    http://www.unboxfresh.com/computing...md-r9-380-nitro-graphics-card-macpro-2010-51/

    Fast renders / exports, everything is very smooth and the card is very quite compared to the flashed 7950 that I briefly used from MCV

    Using it in a 2010.
    I had to take the baseplate off - it just won't fit but this was v easy - a few Philipps sized screws

    Thanks! How does the R9 390 compare to the 380?

    I went with reference cooler RX 480 8GB. Dual setup has been running in my 5,1 since mid July. With 10.12.1 drivers, it's been very reliable.

    Thanks for the info! What do you mean by "reference cooler"?
    EDIT: I'm also following your thread about the RX 480. Thanks for all the great work and the guides! Much appreciated! :)

    Reference = the way manufacturers intend their cards to be. For the RX 480, it's 1266MHz and 2000MHz memory speed with a cooler that looks like this.

    Thanks again! I just ordered the XFX Radeon RX 480 XXX Edition 8GB. I'll keep you guys posted and give an update on how the card performs when I get it up and running!

    Currently as we know the most stable is XFX RX 480 GTR.

    And is that being powered by a single 'Mini PCIe 6-Pin to PCIe 8-Pin' cable? I see from the specs that it's only supposed to draw 150W.

    Actual power draw has not been tested by reviews, apart from one youtuber, who decided to test it with MSI Afterburner. And it was drawing 20-30W less for the GPU die only than other RX 480 GPUs.

    RX 480 GTR requires 8 pin connector.

    Just installed the XFX RX480 XXX and I have to say that I am really happy with the results so far. I followed theitsage's guide and so far so good! One question though, because of the backplate I could not get it to fit in the first PCIe slot. Is it safe to remove it? Will this affect cooling?

    Backplate is more for looks and the heft it gives to the GPU than cooling. I removed the one from my RX 470 in order to make it fit in Slot 1.

    Just a heads up I have 2 of these and under windows they will pull too much power for a single pcie power cable. If you use under windows and or your planning on using just 1 card do yourself a solid and run 2x6 pin to 1 8 pin to ensure you don't have any weird shutdowns...

    Thanks! I am planning on running just 1 card for the time being. But the 2x6 pin to 1 8 pin sounds like a good idea.
    I don't think the 8 pin connecter would fit in the card.

    Is there a work-around for getting 2 mini 6 pin connectors to fit?

    A single 6-pin connector is fine.

    Early cards had an issue with too much power draw, but that was over the PCIe slot anyway, not the supplemental power sockets.

    Aren't Apple drivers for the 480 still only using 8 compute units?

    16 out of 36 CU. Here's the difference in terms of performance of these GPUs in macOS vs. Windows.

    Damn, hope someone can find a way to get the additional CUs enabled or Apple decides to allow a toggle for the CUs for power/performance.

    If Apple did it, it'd probably be for Metal performance anyway, not OpenCL?

    (16/36)*44379 = 19724

    In fact, I am very surprised only 16CU are working but still able to achieve this performance.

    Is this the XFX card you are referring to?

    http://www.newegg.com/Product/Product.aspx?Item=N82E16814150770

    There are two XFX GTRs. Would either give stable performance?

    Are there any powers concerns when running one XFX 1338MHz?
