The installation is not very complicated, provided the computer case is not too small.
Old map and get a new card in. Connecting cable is not a problem because the plugs are coded by their shape. Once eight pin and one six pin. Since you can not do nothing wrong.
The power supply is from my "be quiet!" - Power supply with 750 watts.
After the first start with the new card I first downloaded the latest driver from the NVIDIA HP. Makes sense to use the latest drivers, because on the CD / DVD is usually never the current driver. After completion of start once new and have the new card is fully operational.
Some report to loud fan. I can not confirm. The GTX 260 was very quiet, even under full load. The GTX 970 is only a small tick louder because she has also 3 fans.
In the Game CoDAW all values are set to maximum and I could not find that these fans were noticeably louder such as in CoD4 or ETS2. Even in other games that have all Maximum settings, is heard no noticeable change.
I have 3 additional case fans with 140mm diameter of Enermax with "Twister Bearing Technology" (fan blades hovering in the magnetic field), these fans are very quiet.
The fan on the graphics card are not loud !!! But who thinks that going it completely without noise in fans, is on the wrong track. Finally, many cubic meters of air are moved at high speed. Because it can sometimes lead to noise development. ;-)
From the performance of this graphics card'm already impressed. No stuttering or other errors while playing. Everything runs smoothly at maximum setting.
At the moment I am very happy with this graphics card. Therefore, I can give a buy recommendation here.
