Oboe, the new and especially used market for 970 will be very attractive next month. Even now I've seen good 970 cards go for 150$ USD here in Canada, and there are PILES of them for sale on various hardware/gaming forums up here, lots of opportunity to make offers and get even better deals. 970 IMO for the purposes of this game, and many others, will suffice and then some for years still. Bonus is for another bit of $, the 1070 will let you run everything out there at max and expect longevity for quite a while.
