In all honesty one 1070 compared directly with another 1070 there will not be that much of a difference. 2-4 FPS that's what we are talking about here so my suggestion would be go with the one you trust more
i don't find that to be true. I have a g1 gtx 970 gamer edition and I have bought and built 3 other systems with other oced 970s so I could compare 2 of the 970 g1 gamers I bought managed to go up to 1522 and 1497 that alone is the small difference of 3-7 fps in some games but looking at other oced cards was higher. They couldn't even reach 1400s well and were 10-15 fps less at least. Hell it was the difference of the whitcher 3 having2 settings turned down to very high (Rest on ultra on the g1 970) to 4-5 settings turned down on other lower oced cards. To me that extra 20-140 hz makes all the difference when I'm paying the premium for a model gpu. That what I pay for, the luck to be taken mostly out of the equation and have a cherry picked gpu. IO find it reasonable to have a 40 uk pound increase for this.
a good example is gta 5 with my 970g1 I ouly have to turn down 2 settings in ultra to get a steady none moving 60fps.
Other cards ws like 45-57 until I turned down 4 settings in order to achieve 60fps, its that kind of fine tuning I th9ink of when I buy my card oced.
I'm looking at 1070s when prices fall and the choices so for for me is zotac apm extreme and g1 gamer gigabyte, but bias and knowledge falls on the g1 faver and why, well I know g1 cards use gauntlet which means they pick the best gpus that run the best oced for this g1 card, the zotac doesn't tell me they do so I'm guessing maybe not and cherry picked gpus means yourt getting the top end of those gpus, so a lot of the luck taken out., that's a game breaker for me. I hope the zotac card does cherry piuck the gpu but truthfully if they did it would be advertsised across the board. The other issue too is heat pipes as cooling is a big thing to me. Gigabits 2 coperpipes treatchm out into a massive copper plater that touches the gpu that's direct gpu contact and it works incredibly, ive yet to find out if zotece 6 pipes directly contact the gpu or and ram like gigabytes do as there are no reviews on you tube.
personally id rather have the zotac because its a little cheaper and well better looking fans wityh rgb lighting where as g1 puts orange stipes on its fan aray and they are not like the 970 metal, they are now plastic, both these things turn me off the g1 card.
