Good quietly powerful graphics card of the middle class

I have this graphics card is now about 3 weeks in my PC in operation and can now draw a direct comparison with the previously installed graphics card GeForce GTX660 DirectCU II a Asus OC.

She, unlike the GTX 660 a second 6-pin power connector and draws a little more power, but my 550 watt power supply yet loose (Intel i5 4670K, MSI Gaming G45, Standard components) is sufficient. It is not quite as quiet as the Geforce, but still absolutely silent even under full load quiet and cool. Spulenfiepen or similar I can not hear. The performance in games is obviously a bit more than the GTX 660, but the performance gain is kept within limits, so the upgrade is worth mE does not slow. The image settings via Catalyst CC is not quite as comfortable as Nvidia and now and then I have a USAGE or game nacheinstellen a little. With NVidia adjustment ranged from globally for all applications. Nevertheless, I am very satisfied with the graphics card, for almost EUR 165, - the PL is very good.
