On what BUDGET ? For which target Screen Resolution, 1080p ? Which PSU are you currently having ? Also, please provide FULL PC specs, most importantly the make and model of your CPU and PSU.....
GTX 1050Tis currently start at around $170. If you expect a significant boost in performance, you'd need to add around $80 to make it worthwhile and assuming you already have the power supply to power the new card as well.
