Quoted OC gain is 13% (I'll round up to be nice), let's compare The Witcher 3 at 1440p:
64.2 * 1.13 = 72.5
Lower than a "stock" 1080, much lower than the MSI GTX 1080 Gaming at stock.
Again, 34.2 * 1.13 = 38.6
Raevenlord said "the GTX 1070's performance can easily be overclocked to reach a stock 1080," but even at 2100 MHz and maxed out memory, which is the very top end of a 1070 overclock, the 1070 falls short. And that's
assuming that these games would scale as well as Battlefield 3 does with the overclock. Not likely.
Can the 1070 approach a stock 1080 when max overclocked with a prime chip and memory? Yes. Can "the GTX 1070's performance... easily be overclocked to reach a stock 1080"? Not by any objective reading. Raevenlord is trying to make this a 970/980 situation. It's not. If he took out the "easily" qualifier and explained his methodology I'd be fine with that. Until then, it's just a half-truth.
