I can tell you from experience of owning both cards, I first bought the EVGA Geforce GTX 1080 FTW because of the design of the card and the reputation that EVGA seems to have on the internet, and i was amazed with it when i installed it, having said that. After 2 hours of gaming my monitor went black, and the whole computer froze up, and the fans on the graphics card sped up to 100%, i tried several things to fix it thinking it was over heating, after a few hours i simply returned it for another FTW card, installed the second card and it worked for about 3 weeks, then one day randomly it dit it again, black screen, fans sped up to 100% fan speed. I returned the card again and purchased the Strix 1080 and have had 0 problems with it, i upgraded from a Asus GTX 560 that i had for 5 years as well that had 0 problems with. So yeah after all that id say go with the Strix, lol sorry i had to vent a little, hope this helps you decide.
