I can't imagine why you'd want to buy a beefy SOC with unified memory, only to have it host a discrete GPU through it's narrow PCIe x4 interface. You'd be better off with a traditional CPU that supports a proper x16 slot.

If you want to try both "Team Red" and "Team Green" stuff without having 2 hosts to manage, the x4 interface is a reasonable tradeoff.
