Question about ASUS GeForce GTX 1080 STRIX O8G GAMING

This card has more power connections and a better cooler (if this fits in your case). It also has a boost clock of 1936Mhz by default, the "normal" one only has 1733Mhz. And of course RGB LEDS ;D
Hope this answered your question, in my eyes this is completely ok for a surcharge of 50Fr.
