Those buying used, do you mostly have good luck with your purchase? I'm kinda weary dropping 500-600 and have no refund. My wife informed me she was getting me a 4k display. Unfortunately I still game on a 980ti. I was just ooking at new egg and the new 1080 ti's are the same price as 2080 ti's. I could do it but there is no way I'm paying that much. I also noticed that in every cards reviews people are still having problems with their 2080tis. so anyway, you guys have much luck with doing used ones?
