Now the graphics card itself:
I have games like: Assassins Creed Unity, Call of Duty Advanced Warfare and Far Cry 4 on Ultra also tested for several hours. Only when Call of Duty Advanced Warfare were slight stuttering. But these are the game self-inflicted.
The graphics card runs extremely quiet. In Desktobbetrieb she even turns the fan off completely. I hear them not even under full load. (Spulenfiepen, as some describe, there are with me not)
And last but not least the temperatures. In Desktop mode it reaches when it comes up 27 ° C
Under full load, it is then so to the maximum of 55 ° C
So all in all perfectly fine in my opinion.
Recommendation from me in any case. The GTX 980 is here perhaps only marginally better, although I can not draw any comparison.
I can only say that whoever wants to have a next gen graphics card, can access peaceful here.
