At 1440p the 1060 beats the 580 in 3/10 games for average fps, and 5/10 games for minimum (which you previously state is the more important metric to look at).So gta5 is the only game that's nvidia friendly to the point where the 1060 actually beats the 580.
On average, based on the results for 1440p in that link, the 580 has 3% better min fps, 5% better average fps. 3-5% better on average is a far cry from being "a whole lot better". So, as I said previously, it's a bit better overall on average, but not by a large margin.And average wins are higher at 1440p.
It shows that it is a slightly better card. And yes, if it's a $100 cheaper then it's even more obviously the better choice. Which means there's no need to exaggerate the performance of the 580 by saying it performs significantly better and is in a whole different performance class than the 1060.But as your link clearly shows, thank you for that, the 580 is the better card, and at $100 cheaper, by far the better deal.
