980ti or 1070

[Chillkroete]

Currently working with one 960 (4gb).
Which of these should i buy?

In near future i want to add one more.... so the advantage of the 1070 is that it only needs 150w and has 2 gb more of ram.
Is there a big gap between the 980ti and 1070 when it comes to speed comparison
(i know that there are no official benachmark results of the 1070, but maybe someone has some experience).

and is it always the best for mulitple gpus to stick with the founders edition?


cheers

For now the winner is 980ti but who knows how fast will 1070 be when Octane will be fully optimized for Pascals. Power draw of 1070 is really tempting.
