Gainward will not be overlooking the GeForce GTX 960 GPU and it has already launched this very GPU under the name of Phantom. The stock Nvidia GeForce GTX 960 works at 1,165 and 1,228 MHz base and boost speed respectively while the Gainward GeForce GTX 960 Phantom works at 1203 MHz base and 1266 MHz boost speeds. There is another model called Gainward GeForce GTX 960 Phantom GLH that operates at 1279 and 1342 MHz base / boost speeds respectively.
The maximum TDP still does not go more than 120 watts so a six pin power port works just fine. The GPU will go up for sale for 200 dollars / euros. Folks at Nvidia say that you will get twice the performance of previous-generation cards thanks to use of Maxwell architecture. The Maxwell powered laptops will probably be higher than 45-50 percent over Nvidia GeForce GTX 660 and around 10-15 percent over GTX 760.
Gainward GeForce GTX 960 Phantom come with removable fan design even though the stock board does not come with one.
