Great. So with IGP and RX 460 connected to the same monitor you get the pre OS screen (with bios and boot drive selection) and the right OSX screen with no problem...not really a pita in my opinion, just 1 more cable

So my question is, with two cables..both connected to the same monitor. (One from RX460+Mobo (HD530))...What is driving the display? Is it the RX 460...or is it the HD530?

I just built my first Hackintosh.
i7-6700, Gigabite GA-Z170x mobo
2 x Sapphire Radeon Vapor X R9 280x
G. Skill Ripjaws V series 64gb memory

I built it solely for FCPX use. I've got the FCPX 10.3.1 installed but after opening the program, it crashes after 2 clicks on anything.

Any help for a newbie would be appreciated. I'm afraid I just wasted $1800 building this if I can't get this to work.

thanks.

A hearty holiday THANK YOU to Fl0r!an and so many others for this and other posts that helped me get Final Cut Pro X editing back on track. My third build is now shredding video edits with stability and ease after I swapped an Nvidia GTX 760 for an R9 280X card. The fix also included replacing a failed 120Gb Sandisk SSD (12Mbs write speeds) with a 250Gb Samsung 850, adding a 500Gb Samsung 850 for video projects, installing Sierra and upgrading from a 620W power supply to a Corsair RM1000X for the 280X and a case full of drives. It did the Brice X benchmark in 26.7 seconds. Luxmark scores 14774 and Cinebench 124.9 for OpenGL and 858 for the CPU, but I think that will improve if someone can help me figure out why the i7-4790K CPU isn't boosting past 4K.
I'm running a similar setup as you. i7-6700 with dual R9 280x but FCPX 10.3.1 is crashing. any help how to fix that?

So my question is, with two cables..both connected to the same monitor. (One from RX460+Mobo (HD530))...What is driving the display? Is it the RX 460...or is it the HD530?

This is a good Question:
On the Output, driven by the HD530, i see some flickering artifacts on the upper left, which is a known bug for the HD 530 running on Sierra. These artefakts aren't available on the output from the RX 460. I think each gpu renders it's own output.

If i use final cut/photoshop I can see that the RX 460 ist used for gpu acceleration (iStat), which is the only thing I care about. I think it doesn't matter which gpu renders the user interface/which one is used for the output if the RX460 is used for the use cases I bought it for(GPU acceleration).

After wake/sleep the HD 530 isn't active any more. In this case the RX460 must be used.

I have a question:
Time to upgrade my GPU because gtx 770 dead (artifacts and hangs in any OS), if i could use Pascal gpu i will definitely buy gtx 1060 because it's little bit cheaper and i always use nvidia, but there is no really info when drivers will be released.
So RX480 will work good? or still it's like x3 times slower than it should be?
I just need Final Cut Pro X working good and some other video and photo software.
I can edit clover config if needed, thats not a problem.
Thanks.

@drumm ,

To get the 480 functioning you will need to set the iGPU as primary - doing this can introduce problems in FCPX. For FCPX the best cards remain the 7970 and the GTX 280X at this point in time.

That's bad, maybe nvidia release drivers for 10xx series. don't want old GPUs
Anyway, thanks for info :)

I have a 6870 under Yosemite and I was able to patch the AMD6000 kext to get both dvi ports to work. I used the ati-personality.pl script to get the offset. The framebuffer was Gibba:

unmodified
0000000 00 04 00 00 04 03 00 00 00 01 00 00 12 04 05 01
0000010 00 04 00 00 04 03 00 00 00 01 00 00 22 05 04 02
0000020 00 08 00 00 04 02 00 00 00 01 00 00 11 02 06 04
0000030 00 02 00 00 14 02 00 00 00 01 00 00 00 00 03 05
0000040 04 00 00 00 04 02 00 00 00 01 00 00 11 02 01 03

Patched
0000000 00 04 00 00 04 03 00 00 00 01 00 00 12 04 04 01 ---- DP 1
0000010 00 04 00 00 04 03 00 00 00 01 00 00 22 05 05 02 ---- DP 2
0000020 00 08 00 00 04 02 00 00 00 01 00 00 11 02 06 04 ---- HDMI
0000030 00 02 00 00 14 02 00 00 00 01 00 00 00 00 03 05 ---- DVI 1
0000040 04 00 00 00 04 02 00 00 00 01 00 00 11 02 01 06 ---- DVI 2

Now under Sierra, I find that the ati-personality script does not work, so I found the php script mentioned earlier in this thread.
https://www.tonymacx86.com/threads/apple-intel-amd-ati-framebuffers.112299/

However, I can't match the unmodified framebuffer Gibba with the one in Sierra.

I tried putting the above data and patch in clover, and of course it did not work, that is when I started to look at the kext.

Your best bet for a new card at present is to pick up a GTX980 or 980Ti which work from Yosemite with the additional drivers. Powerful enough for decent 1080P gaming. It is likely to be a few months before we really see any more GPU options within macOS.
I run a dedicated FCPX machine as it gives me better flexability.
