Dual 5k displays using two Vega 64 graphics cards?

[misterwiggles]

Planning an X299 build based on @kgp Mojave build guide. I have an existing LG Ultrafine 5k Thunderbolt Display that I plan to use by routing the DP output of a Sapphire Vega 64 card INTO a ASrock TB3 card with the final output TB3 cable connecting to the LG Ultrafine. However, I plan to buy the new LG 34 inch 5k widescreen when that ships in September and want to run a dual display setup. The new LG widescreen has a single DP 1.4 input. So if I use TB3 for the Ultrafine can I just add a 2nd Vega 64 card with DP 1.4 output and just plug it into the new LG widescreen using DP 1.4? I haven’t built a Hackintosh prior so am unclear on whether dual displays are possible using two AMD graphics cards like I am proposing. Any help here would be appreciated. A guy was kind enough to guide me on the TB3 part of this but I still need help on driving the 5k widescreen in addition to the Ultrafine. Thanks!

As I say in my post, I don’t have any hardware as this is my first build. Doing research on what the build should be.

The Vega has DP 1.4 ports.

So to drive one 5k LG ultra fine and one 5k LG widescreen you need a single Vega with 3 DP ports. Any Vega will do, just not the Saphire one as it only has 2 DP ports.
2xDP 1.2 output are connected to the TB3 card, which then is connected via TB3 to the LG screen.

Thank you. Even easier and less expensive than I thought. I’ll start looking at Vega cards with 3 DP config.

Did some searching but the only Vega 64 card I could find with 3 DP outputs is this one: http://www.xfxforce.com/en-us/produ...64-hbm2-8gb-3xdp-hdmi-silver-fan-rx-vegmtsfx6

Any others to recommend?
