Forget the 870M. If the 860M is a Maxwell part then it would be nice to have a 970M but then cost would rise even more.
According to reviews, it's Maxwell. At least in FHD versions, but why would they change it in UHD one?
Its Acer if they lower build quality then they be building potatoes.
In general, yes, but it's decent enough here, according to reviews.
If you get decent frame rates at 1920 with 2x AA turned on. You will get the same or faster frame rate, at the same or better latency, and a better image at 3840 with 2x AA turned off.
Umm... just... no. No, you won't. It doesn't work like that.
So what is the point of a 4K laptop that you have to scale down to make a game playable?

It's for people with interests other than gaming, such as photography and video editing. If you don't need that, IPS FHD version is waiting for you. Good brightness (avg. 319 cd/m2), rather deep blacks (0.46 cd/m2), quite good color accuracy (about 5-6 DeltaE 2000), 75% sRGB, no blue tint, matte. Great for gaming.
BTW this laptop is using an M.2 SSD and a SATA HDD for storage so you get best of both worlds - something many competitors (looking at you, Asus) STILL don't offer for some stupid reason. Default Atheros WLAN card sucks as usual, buy config with Intel or Broadcom or change it yourself. Maintenance sort of annoying, have to take off top panel for access and not bottom. Good speakers (4). Clickpad's kinda glitchy like in V5-573 but tolerable. Port arrangement is stupid, everything on the right side - sorry Acer, but lefties are a tiny minority, this is uncomfortable. Overall, a good laptop. Definitely better than expected from Acer and better in some aspects than many alternatives with 860M.
