After my previous comment, I realized something (yes, I'm that slow)
The GTX 1080 Founders Edition is $699, that translates to roughly 789 € over here, a 13% increase.
If we apply the same percentage to the GTX 1070 and its $379/449 price tag, we end with a card that will cost from 425 to 510 €! That's insane!
Suddently, AMD's $199 RX 480 that will translate to roughly 225 €, becomes a better looking upgrade path (or the 8GB model, that even if it costs $249 it will be about 285 €).
Please excuse my bad English.
