No, One was my own personal card (the smaller, EVGA card) that I used for gaming and work over a span of about 3 years.
The Asus card I picked up from a friend, thinking I might use it in tandem with the one I already had, but It didn't pan out. I can confirm that it functions but I never stress tested it, but as far as I know, it was used for very much the same purpose, and for roughly the same span of time, give or take about 6 months.
Im getting rid of them because with the recent 1660 announcement being a bit of a letdown, I expected 1070 prices to skyrocket and figured now would be the time to get one. Not entirely sure that happened...but here we are.
