Imagine that your shiny new Titan Xp has gone bang. While you're waiting on a replacement, you have to use your GTX 1050 Ti. Which of your extensive library of older games will run at a solid 60 fps at a good graphical quality on your 4K monitor?
Not terribly familiar with the 1050 Ti, but you might be able to swing Overwatch. It runs right around 60 FPS for me at 4k with almost everything turned up (No DSR, obviously - I think the only other setting I tweaked was some kind of AA) on a 1070.
