Thanks for telling us. I've been wondering how the 1060 would do with my 2560 x 1600. Your comment makes me believe the workload wouldn't be an issue.
You're welcome Bizman. My take is the 3 GB GTX 1060 hits the sweet spot for max performance for the money, similar to the i3 6100 for cpus. Which is great of course as long as you're getting what you want out of them. I'm a tad bit disappointed that the 1060 doesn't max fps all the time, but I remain overall happy with my choice.
Most of the time my fps is maxed out at max graphics setting running the DX11 version of AH. I get better performance with AH3 DX11 over the DX9 version, and it seems I've stopped getting the occasional petite-freezes since the last update. On some maps and in high density player situations, the frame rates take a hit, but so far have never noticed a hit to an unplayable slowness, and it sees quite easy to adjust the graphics setting down a bit to accommodate the GPU load. I've only resorted to turning down environment mapping so far, and frankly can't say I see a difference in eye candy. My impression so far is that the 1060 is be fine for 1440p. My i3 CPU by the way seems to keep up with the load, and the 1060 seems to be my fps-limiting hardware below 75 fps. My guess is that if in the future I venture into VR, I may want to upgrade to a 1070 or more, but would try my existing hardware first. If I decide to upgrade, my son who lives here locally would love to have my 1060.
So bottom line, so far I'm happy with the 1060 for 1440p.
