Question [GTX 1080 FE] (620euro new) VS [2 X GTX 980ti] (620euro used like new) ???

I would take the 2 cards, the 1080 is slightly faster than 980 ti and you can get 2 of these. There is nothing to think about.

I would take the two 980 Ti's. Try SLI and if you don't like it sell one of them for what you paid for it.
