GTAV is of reasonable price now in Steam sale, but I have been avoiding buying it as I'm afraid 1050Ti is not enough to enjoy from it at 60fps, also I'm not that keen of online gaming and don't know how well one can enjoy that as single player.
I run the game at 60 FPS with a mix of high and medium settings 90% of the time with the specs in my signature, so yeah, with the 1050 Ti you should be fine.
