This conveniently ignores all of those gamers with high refresh rate monitors. Anyway, we now have detailed benchmarks for Gears of War 4, so we can finally make a good analysis. GTX 1080 is
29% faster than the GTX 1070 in the 1% low metric..
He didn't test insane settings, but the point is, for high performance gamers, the GTX 1080 will obviously offer a much better experience than the GTX 1070 at 1440p ultra:
No high end card is worthy of its price premium. No matter how many times we tell you, you just don't get it. High end cards are not about price effectiveness. They're about bleeding edge performance!
The GTX 1080 is on average about 20% faster than the GTX 1070. The Titan XP is on average about 20% faster than the GTX 1080. But when you look at the minimums, the gap is often larger as the Gears of War 4 benches above demonstrate.
The larger gap in minimums can make a
HUGE difference in whether a game stays above 60 FPS, or drops below it. Case in point:
As demonstrated by the benchmarks above, the GTX 1080 does offer a measurably superior gaming experience, because it allows most games to be played at above 60 FPS at practically all times on max settings at 1440p. In Gears of War 4, a GTX 1080 would be much better for someone with a 1440p 120 or 100Hz monitor than a GTX 1070..
Again, you bring up price effectiveness for a premium product geared towards people that care only about performance. Price is most likely a secondary concern for the people that are buying these products.
I don't even know why you're harping on the GTX 1080. The Titan XP is a far more egregious offender for price effectiveness than the GTX 1080..
