Finally the Sapphire R9 Fury has arrived. Part number 299-1E331-100SA.
The card is 12 inches long and it wants dual 8-pin PCIe cables. The HX1000i has lots of connections for two of these cards but in this day and age with dual card support waning one card is adequate given the performance. The card was released on December 16, 2015.
I reinstalled Windows due to the brand new MSI X570-A PRO motherboard and I had to call Microsoft support to be able to activate Office 2013 again. Windows itself activated fine with my Hotmail account.
GPU-Z shows that the R9 Fury has lots of performance left in it for gaming.
THE CARD FAILED
After installing Windows and installing Office 2013 things were fine. Steam installed and testing some game benchmarks were fine as shown.
Then the machine crashed and would not restart. The red video card light on the motherboard was lit and the card would no longer work. The fans are dead and the front button is supposed to glow blue, does not work either. In short this card, for some unknown reason, dropped completely dead.
I have subsequently removed the R9 Fury and have returned the RX 480 pending a different card.
