^Has the game that many cutscenes?
Anyway, after reading (and by reading I mean mostly looking at the charts) several GTX 1080 reviews, I come to two conclusions:
1-Performance, and I'll use a graph from the TechPowerUp review: http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080/
Note, I use the 1440p graph but it's basically the same at 1080p and 4k.
The GTX 1080 is a worth upgrade for those who have a GTX 970 (it's almost wtice as fast) or lower. The with a 980 or something better, it's only worth it if you need more power.
2-The Founders Edition is a total rip off. The cooler can't keep the card temps under control and limits the max boost speed of the card. See this graphs from the [H]ardOCP review: http://www.hardocp.com/article/2016/05/17/nvidia_geforce_gtx_1080_founders_edition_review#.Vzxt2-R9VxN
It's easy to see how the frequency goes down as the temp. rises, until it stabilizesaround the 1770MHz / 82ºC.
It's better to wait until cards with aftermarket coolers start to appear, which may also be cheaper.
Please excuse my bad English.
