The only reason I suggested it was because it was cheap and it would work well with the CPU. I've had a lot of issues trying to use a GTX 960 with an i7-950. Sorry if I'm a little biased with my answer, but swapping a 960 in that build with a 1060 makes a half FPS average difference. And it's actually half down, not up. This was across testing of more than one, and they're not poorly optimized.
Going down a notch brought me at the 760 Ti, which surprisingly enough can still pull ultra in a lot of games.
Sorry if I didn't know, but it's what I've learned from experience. I'll need to check those FPS counts again. They don't sound right anymore. Too bad I've sold the build to a friend. Probably could get a few scores from him.
Don't listen to my ramblings right now No0b_with_pc, I'm just being an idiot.
