just want to mention, that if he uses rx570/580, then there may be delay because companies can't supply enough of those cards yet.

i'm from canada and i have 2 rx570 BO from exactly a month now, and i would love to order 12 more right away but no one has in stock.
they all say; place your orders and we will ship asap. but why would i do that and start paying interest on my CC...
anyway, just a minor detail i think that could be causing the delay.
