Pros: At least as fast as one 780Ti.
Cons: RMA'd the first card because it was hitting the temp ceiling of 75c and throttling the GPUs from 1018 down to 850 -900mhz.
Replacment card has the same heat issue but less throttling for some reason.
I have a corsair 1050w PSU. I tested the wattage from the wall with a Kill A Watt meter (can buy from radio shack for like 20 bucks) In Heaven benchmark Firestrike Extreme, BF4 max settings-full 64 player server for an hour, Crysis and Star Citizen.
This with an AMD 8350 @ 4.7 and 6 case fans plus LED's.
The wattage never went above 825 and averaged about 720-780 watts at load.
I think the issue is my CPU and its lake of single threaded performance.
AMD advertised this as a the ultimate gaming card but neglected to mention a 20-30 percent bottleneck in performance with thier most powerful CPU's.
If you look at most benchmark and gaming review sites on this card the testers are all using $600-$1000 I7's to get the results we see with the R9-295x2.
If you plan to get this card I would recommend wating until you can drop $1000 or more on an X series I7 and a new motherboard.
Pros: Dual Hawaii GPU's. Single card supposed to be more powerful than a Titan Z or dual 780ti's.
Cons: In Crysis 3 and BF4 the GPU temps hit the 75c ceiling every time As a result the stock core clocks of 1018 drop down to around 850. Massive performance hit.
I have 7 case fans (side, front,under,and rear intakes) as well as top exhausts. So its not my case airflow.
Other Thoughts: A non-refundable $1500 upgrade that runs 15-20% slower than what I upgraded from.
