If you have an GeForce GTX 960 you may have considered using it for bitcoin mining purposes. This GTX 960 is likely not the best card for mining in the long run. The power consumption of the GeForce GTX 960 is only 20 Watt less than a GeFroce GTX 970, but 40-50% less on other things. The performance result from the GTX 960 are in the range of 1.5x to 2x compared with GTX 750 Ti. The Nvidia GeForce GTX 960 card GPU mining could be an alternative to the GTX 750 Ti series.
You may be too late to make huge profits with GPU mining. If you are serious about mining you will need a mining farm or dedicated hardware. GPU mining in general seems to be on a decline, read this thread. One of the miners writes:
I think GPU hobby mining was redundant long ago.When I started mining BTC back in 2011,with a Radeon HD6950 it was an exciting hobby for me as I was able to tweak my GPU with a ridiculous overclock as well as unlocking the shaders,on top of making a lot of profit without having to think too much.I also ended up signing up to the forum and learning a lot more about the mining business so I feel quite happy that I came across this forum when I did.If it wasn’t for that,I wouldn’t have been mining for as long as I have now.
