Rocking a Sapphire Pulse RX 580 8GB. It's performing so well that I'm considering selling my HD7950 since all it's doing now is taking up space in a drawer.

But you still has at least one Mac EFI GPU on hand for emergency, right?

(I also sold my Sapphire HD7950 Mac Edition with a very good price, but I still have a GT120 and a HD4870)

Yeah, I've got a GT120 in a drawer...just in case! ;)

I appreciate that within Mojave the GT120 may not perform very well, but if will be more than sufficient to save my skin should I ever need it.

I'm running an RX Vega 56 in my cMP, but still on 10.13.6 with the 138 firmware from Mojave. No issues so far!

Although I noticed that it is showing it running at 8.0 GT/s... is that a cosmetic error?

Self-flashed MSI Gaming 3G R9 280X in one machine, EVGA Mac Edition GTX 680 2 GB in another.

Maybe will pick up a RX 580 or even a Vega when the prices come down just a little bit more.

Have seen several MSI variation RX 580 8GB's fall under $210 USD recently, which is cheaper than many of the same/similar 4GB versions. The Apple recommended Sapphire PULSE RX 580 (8GB) was $240 USD on sale a few weeks ago.

There are no boot screens on the RX 480 RX 580 cards, although apple might allow it as its a supported card, unless there is to be an apple version of the cards of course.
R-9 280X is the last one to have EFI, so any newer card don’t have boot screens/selector/FV2 support.

Anyone with one of these??
Radeon Pro WX7100
Advantages: single slot height, 6 pin power connector, same chip as RX580 (I think)
Disadvantage: cost, cost, & cost. :)

Anyone tried a MVC flashed NVIDIA GTX 980 TI 6 GB running Mojave?

The MVC web page indicates that it should be compatible.

I have an MVC-flashed NVIDIA 1080 Ti 12GB. Anyone have any idea how this works with Mojave? And how does it compare to a 580 Pulse?

For those with newer flashed NVIDIA cards, would wait for NVIDIA Web Drivers for Mojave before relying on the cards. Some basic functions work, but a lot is hit/miss from what I’ve seen and read. GTX 680 is better than some others.

If Beta testing, would recommend RX 580 over NVIDIA right now.

Should work once the web driver available. Anyway, 1080Ti should be 11GB, not 12GB.

I have both 1080Ti and 580, both can run the 10.14 installer. For performance, really depends on your workflow.

For FCPX, RX580 is much faster.

For 3D, 1080Ti do much better.

For most other compute job, 1080Ti is noticeable faster.

For OS UI, can’t tell the difference in smoothness (rendering at 3850x2160 HiDPI 144Hz), but 1080Ti cannot do 30bit colour, otherwise some blue will become orange. RX580 can do 30bit perfectly.

RX580 has better power management in some 3D apps. Not becasue it’s a lower TDP card, but can clearly see that the driver has better control of power consumption. e.g. when making 3D drawing in 3D-coat, RX580 only draw high power when there is something change on the screen (like Radeon chill in Windows), but 1080Ti will constantly draw high power.

Since you have a flashed card, so you can have boot screen, utilise FileVault, etc which the RX580 can’t do.

using an unflashed HD 7870 IceQ Turbo, just working great.
would like to flash it, but i am not sure how to do it and if it is worth the risk to kill it.

One thing to note is that, as it stands, FileVault won’t be available to cMP owners in Mojave regardless of whether the card is flashed and shows bootscreens or not.

Some people have them. They work well from what I’ve read. Based on RX 480. WX 8200 is a much better deal.

Sold the flashed HD 7950 for €125 yesterday, nice! It went to a guy who only wanted it for Windows. Tried to explain that the price was higher (usually €90) due to the EFI, but he didn’t care.

So now it’s the RX 580, with my GT 120 safely in a drawer in case it all goes nipple skyward.
