Hi Ferris

I've been looking at those card for a couple of days, do you know how many watt they consume from the wall?

I would assume they should at least be hashing with 700 kh/s and watt consumption at 200watt for each card.

A normal 7950 card:
Memory Clock   5000 MHz
Memory Size   3072 MB
Memory Bus   384 bit

Yours:
Memory Size 4096 MB Size
Memory Bus 256 -bit GDDR5
Memory Clock 5600 MHz Effective


Faster memory clock, but not being able to transfer at the same speed - but 1 gb more when it does.. 


I have Gigabyte underclocked R9 280X they consume around 230-235 watt each card and produce 705-710 kh/s
