My first impression.
I ran it next to a Sapphire R9 290X 8Gb Mem, hash rate was almost exactly the same. If you didn't know they were different, you wouldn't have noticed.
What it "did" very well, and yes, it "did" it.. haha, was OC, Sapphire is known to be able to OC very good.
This was no exception.
+ that it stayed almost 10degrees cooler then the 290X
Maybe that's a coincidence, maybe not.
10 min after i did some tests, i rebooted and it never came alive again.
So for those interested in buying a 390x. Think Twice... Buy a 290x, which does the same thing but cheaper!
As soon as The Fury X arrives (next week it seems) i'll be posting my findings.

This is a bit thin, what you say here (and I am not defending amd or else... as I am rather an nvidia guy...).
