You can play all games on High at 1080p with that card right now, but you'll inevitably have to drop to Medium when newer, more demanding games come out this fall, and next year. Then two years from now, you'll probably have to drop some to Low settings.
Nothing is future-proof, but if you're comfortable with selling on ebay, you can get a 75% of what you paid for the card and put that toward a newer card at the same price-point every year.
