I entered my current parts list into a bottleneck calculator and it says a Sapphire Pulse RX 570 could be a bottleneck with my i7 8700k.
I was thinking of downgrading my CPU to a i5 8400 or i5 8600 to minimize the bottleneck or go with a i7 8700 now and possibly upgrade my graphics card ( or add a second identical one) down the line. Previous posts about dual GPUs make it seem possible. In the future is it likely there will still be support for a second graphics card?
MacOS supports dual cards but only for compute and only in some apps. For rendering video it’s great, for playing video games it is not. You lose pci lanes. One card gives you 16 pci lanes, 2 cards gives you 8 lanes per card so in OpenGL apps and gaming have reduced scores or performance. Your best solution is always the most powerful single card in MacOS.
If you plan on upgrading the card later I would go with a RX 560 for just over $100 it’s a great card. Just don’t get the XFX RX 460-560 model it’s the only one that has an incompatible bios. All RX 550 models are a no go as well.
