This is the results of my new Sapphire Nitro Fury, which is the second Fury card that I've now received which has something wrong with it..
The card installed with not one issue using 16.3.1 drivers..
I ran valley benchmark many times over the course of the day and it ran good.. The computer had been up and running for about 10hrs with this new gpu.... Temperature never exceeded 70c at any point in time during benchmarks, at idle 32-34c.. At the time of the distortion/anomaly/signal loss the temperature was roughly 37c.. and I was actually browsing this forum when it occurred.. I unplugged the hdmi cable which was included with the sapphire gpu and plugged it back in and the signal/picture was restored.... It's not the monitor, the monitor runs fine with my other 2 gpus (hd6850 & r9-290) in this same computer and it has ran fine for over a year.
I am certain this is a gpu/driver issue..
Full install of Windows 10 not an update, used my win7 product key for full version of win10.... all up to date with Microsoft
