so i plan on a mini itx build when BR becomes available later this year. with the rather disappointing price per performance of the RX 460, is there any chance the AM4 mini itx MB's will have 2 PCIe slots so i can purchase an RX 470 instead? from what i can find, all of the mini itx FM2+ MB have only one slot. also wondering if the RX460/470 will crossfire with BR/RR APU's?
