Nvidia designed Maxwell to deliver more efficiency and performance, so the GTX 980, GTX 970 and GTX 960 are vastly more efficient than their Kepler-based predecessors. The GTX 980 has a TDP of 165W, the GTX 970 is rated at 145W, while the GTX 960 has a TDP of 120W.

The old GTX 780 Ti and GTX 780 have a TDP of 250W, while the GTX 760's TDP stands at 170W, the same TDP as the GTX 670. Just like their predecessors the GTX 980 and GTX 970 cards are capable of delivering smooth frame rates at resolutions up to 2560x1600, while the GTX 960 is good for playing at up to the 1920x1080. In case you are planning to build a 4K capable gaming rig, you will have to grab a couple of GTX 980/970 cards. The GTX 960 is mainstream card and it supports SLI, however two GTX 960 will be enough for 4K gaming only in less demanding titles.
Compared to previous Maxwell products, the GeForce GTX 960 features an entirely new GM206 GPU. It supports all of Maxwell's new graphics features like VXGI and MFAA, and comes with an advanced video engine.

Like the flagship GeForce GTX 980, the GeForce GTX 960 has a new display engine capable of supporting resolutions up to 5K with up to four simultaneous displays (including support for up to four 4K MST displays). The GeForce GTX 960 also supports HDMI 2.0.
