I think up to 1800, but OC isn't a solution for me. I always buy cards with vendor OC but never OC myself. If I have to OC a card that would just mean it's already too weak. Buying into an extremely cut Pascal now would just make me cry as soon as they release Big Pascal.

But that review compares an overclocked 980Ti with the 1080. A comparison of a regular 980Ti vs 1080 shows that the later is about 30% faster.

Also, a 1800 overclock is a very modest one. That G1 they used in the benches is one of the fastest 980Ti out there, and the G1 version of the 1080 will easily go past 2000MHz.

Which will completely fuck up temperature, noise and efficiency. I'd rather have a moderately overclocked 1080ti which has more resources on a chip to rely on instead of just a weak card torturing its small chip.

I think I will be very fine with a dual 1080ti setup because I don't expect Volta to be that much of an improvement over Pascal. Also Volta does not hit before 2018 and by that time I should have enough money saved to switch over to Big Volta should I have to. With a mere 1080 SLI I would never be able to make it until Volta.

Fair enough.

By the way, here's a link with quite a few more GTX 1080 reviews:

may not be the power jump some where expecting, but its a big price gap. I think its a great power to price jump, great for thse who like to sli.
