I have a EVGA NVIDIA GeForce GTX 680 Mac Edition in a MacPro3,1. It says compatible with macOS 10.8.3 or later, however, with it, I can boot Leopard 10.5.8, Snow Leopard 10.6.8, and Lion 10.7.5, as well as all the later macOS versions. The earlier macOS versions don't have acceleration and can't change the resolution (except Lion?), but they seem to work fine.An RX580 will run at 60hz.
You cannot run Mountain Lion with the RX580 (min Sierra).
Not asking for macOS to recognize the RX580 - only the EFI frame buffer that is used before macOS boots.Natively MacOS will not recognise an RX580 before Sierra.
There maybe a hack with kext files, but your asking for trouble.
that was my feeling. Sapphire is AMD's OEM like PNY is for Nvidia...but I wanted to be careful n check. thanks!I’ve only used a sapphire rx580 and never had a problem.
I’ve heard the xfx cards can be problematic, but have no first hand experience.
I'm interested for this too. MSI AMD Radeon RX 560 AERO ITX 4G OC works perfect in 4,1-> 5,1 High Sierra and later in Mojave. And just for such video playback, Logic Pro X and similar apps maybe Biostar AMD Radeon RX 550 4GB can be enough?anyone know if High Sierra would get cranky if the RX 550 or 560 I get happens to be the 'lesser' variant that has lower memory bandwidth and fewer stream processors than the normal model? seems all the RX 560's for sale on AliExpress are likely the 560D. I have no issues with this as it's simply for video output and for compatibility as HS prefers Radeon over GeForce.
and heck, while I'm asking, is there much of a difference between the 2GB and 4GB RX 550 for video playback? I don't think there will be any 4K playback, primarily 1080p streaming.

Hi all,
I am looking to improve my Steam in-home streaming performance.
I have a Mac Pro 3,1 with dual 3.2 Xeons, 56GB RAM, and a Geforce GTX750Ti 2GB, running High Sierra 10.13.6 (and Windows 10). I am looking to use this machine as a host to stream games to my 2013 Macbook Air so I can play games on the sofa or in bed when I get a spare few minutes - nothing too demanding, I largely play strategy games.
Does anyone know whether it's the CPU or the GPU that does the heavy lifting for the encoding required by Steam in-home streaming?
Nothing I can do about the CPU of course, but would I benefit from a newer GPU for this particular use? The native performance of this GPU is fine, it just seem to struggle doing the extra work involved in the encoding etc. streaming.
I have been considering upgrading the GPU to something like a GTX680 (£45 second hand) or even a GTX780Ti (£75 second hand). I know Radeon RX580 would also be an option but it's more expensive (£110) and I'm not sure it would work in El Capitan, which I would like the option of booting into for troubleshooting purposes.
Any advice very welcome!
Hi, would a AMD Radeon Pro 580X from a MP7,1 work in a MP 5,1?Yes. MP6,1 D300 uses a variant of the same chip.
Running an MSI Radeon RX 560 Aero ITX 2GB here on an original 5,1 6 core 3.33 with 8GB ram. Needed an economical metal card for Mojave and it's smooth and quiet for that. I haven't pushed it hard on gaming, but online reviews claim it can run all but the most demanding games at over 60 fps (likely on Windows), so I would hazard a guess that it would handle the various streaming needs described here.
I can't answer the question on Steam being CPU or GPU intensive, although with your dual cores you're probably in reasonable shape there. Don't know if my RX 560 would run on your 3,1 and work for your video outs or with El Cap but you could check the specs and data sheet here: https://www.msi.com/Graphics-card/Radeon-RX-560-AERO-ITX-2G-OC/Specification (edit: not bootable though, so if you have space look into having both cards installed at the same time. You might have to disconnect video from the RX and hook up the GTX on boot for that to work but others here who know the 3,1 or El Cap better might have ideas.)
So it could be an upgrade for your GTX 750Ti, or an econo alternative to an RX 550 or 580, if you can find one.
Nope. MP7,1 GPUs are not standard PCIe cards and need logicboard routing/muxing of USB/Audio to work.Hi, would a AMD Radeon Pro 580X from a MP7,1 work in a MP 5,1?

Since Mojave, a METAL supported GPU is required for macOS acceleration. GT120 support ended with High Sierra.Greetings all; just finished doing a job for a client with a cMP that had 3 nVidia GT120 cards in it. (Apple part A1310.)
I put a new Samsung SATA 1Tb SSD in, then ran Dosdude1's Catalina installer. I bumped up the RAM to the full 64 Gb, but it still ran very slowly. Found part of the reason was some of the software he was running, but I decided to try a few video cards I had around the shop to replace the GT120s.
A Mac Quadro 4000 would let me boot to Safe mode, but hung about half way through. A non-Mac Quadro 1000 wouldn't boot at all (but I have reason to suspect it might be a dead card,and I'm testing further), nor would a GTX 1050.
BUT! With the right power cables, an Asus RTX-2060 Phoenix booted fine and the system runs very quickly now. System information reports only 9 Mb of RAM, which is odd, considering how quickly it runs, but video seems to be fine, pictures display crisply etc. I'm waiting for him to try it out. (He's a photographer). The 9mb is probably because no KEXTs are running, but I'm impressed it booted at all!
A few details on the box: It's a Mac Pro 4,1 with 2 2.66 Xeons, Mac Pro Early 2009. It's running DD1's Catalina 10.15.5. System report shows the Display Device is Device ID 0x00A1, no KEXTs loaded. Boot ROM version is MP41.0081.B07,SMC version is 1.39f5.
Hope this is helpful, interested if you have any comments.
Not just audio, but sleep too. I explained this today on another thread:and check Audio output is stable. Dual 4.1 have an issue with audio if they run on the stock Xeons.
I am quite sure it can work in cMP. Just a matter of how, and in which OS.will a AMD Radeon 6800 work in a 5,1? Curious since I want to upgrade from Sapphire 3gb to either a 5700xt or 6800. I've read that some people can get away with the 5700xt and no pixlas, but if I'm upgrading (and get super lucky finding) I'd rather get the 6800.
