Also, many newer games, like Elite Dangerous, use "deferred rendering" which is incompatible with standard anti-aliasing techniques, so you really do need to use super-sampling to get rid of the jaggies.
As to the viability of a 1070, I think it depends on the game. Fruit Ninja is probably a lot less demanding that Elite Dangerous, for example. Also, Pimax didn't specify the graphics quality. That means, ED is probably OK with Low Quality settings, which is reasonable, considering that tho 1070 is a the bottom of the acceptable GPU range.
I plan to get an 1180Ti, once it's finally available. I think that anything less will not give me the graphics quality and framerate that I crave.
