As stated in several other treads, putting two aftermarket GPUs in the new Mac pro means you have to sacrifice the Radeon Pro 580X because of power constrains.

The downside of sacrificing the Radeon Pro 580X is you won’t be able to drive a 5K or 6K display that’s currently on sale

Will we get boot screen support with regular AMD GPUs eg. Vegas 56/64 and others or are we going to have the same problem as the cMP build hacking gpu bios etc. If I can get this thing to work with a Vega 64 with bootcamp and boot screens I will order.
