Well, you're correct about the newer architecture, though, I don't think Nvidia's falling short for driver support on older cards - my son has a GTX 660Ti for example, and I recently updated the drivers for him because Nvidia issued new drivers in the past month or so.
However, the 1050Ti is a lesser performer, and the 10xx series cards are very overpriced due to cryptocurrency mining.
If you can find a used 780, 780Ti, 970 or 980 for equal to or lesser money than a new 1050Ti, from someone you think you can trust, then it would be better bang for the buck.
The 1050Ti is a relatively low end card, only slightly more performance than your existing 760. Not worth spending over $200 for a barely noticeable gain in performance.
