People that argue that price of imports won't shoot up are economically illiterate and generally pig-headed anyway, no point in trying to argue with them - the irony is that arguing with them, even with solid facts & good reasoning, just further entrenches them in their position, an unfortunate cognitive bias evolved for a much different effect, called the backfire effect (and btw, not to rain on leavers, it applies to every human; so we're not exempt either). Recommend "The Righteous Mind" by Jonathan Haidt to anyone interested in reading more on it and similar.
Personally my biggest issue now isn't the gpu prices but rather gpu choices. The 1070 looks pretty good but it's Nvidia, which I dislike, it also brings with it a premium for gsync, and it ultimately isn't that much better than a 980ti and which I can find used for much less also; plus I can find a TV with freesync but can't with gsync. On the other hand, AMD has almost nothing beyond a 390 (and soon 480), and crossfire, when it does work, doesn't play so nice with freesync & borderless window, and I certainly won't give up BW.
Too many compromises but I may have to just pay more for Nvidia and be done with it. I guess we'll see.
