It's nice to have extra thermal. It's only 5 bucks but, should i got with the 1080 or 1070 ti?
Edit: I want to see if the https://pcpartpicker.com/product/j8rcCJ/asus-geforce-gtx-1070-8gb-video-card-rog-strix-gtx1070-o8g-gaming would work better. It's cheaper and if I want to do vr in the future it has 2 hdmis.
