    MP 1,1-5,1 Is the RX 580 bottlenecked by the Mac Pro 3, 1

    Yes, I am well aware it's not possible to run macOS with the RX XXX due to the lack of the SSE4.2 thing, however, I use Windows a fair bit, and there are methods to fake the SSE4.2 instruction set by using MouSSE. All I want to know is if its worth getting an RX 580, and using it in my Mac Pro 3...

    Hopefully the people involved with this discussion elsewhere will join in here, as I do think it's interesting conversation, although not entirely appropriate to the original thread. Optimised/proxy media work as I'd expect, this was purely a test to see how working on raw h264 footage would...
