Is a Dell Optiplex 3050MT with an i5 7500 processor and a Phoenix GTX1050 Ti Graphics card good enough for playing current and future AAA video games in high/ultra settings?
At 720p resolutions, yes. But at 1080p and higher, not so much. You'll have to back off a bit on most AAA games' settings from ultra if you want 60 fps+. Again tho, it will depend on the game.
