While technically vapour is correct, but honestly the 1050ti is the cheap alternative. Can you really not save an additional $10-20? From what I've read it would be worth the extra money by going with the 1050ti.
If you really need to pinch some pennies, watch closely for a sale price. Or consider looking for a used card. In the last year I got great deals on a used GTX 950 and a used GTX 970. People are constantly upgrading their video cards.
