GTX750TI 2GB is 60 USD = 300 h/s & 40W - 50 W
GTX1050 2GB is 170 USD = 341 h/s & 45W
GTX750TI is more profitable if thinking about the prices.
Are you sure of your numbers ?
Because Ihave GTX 750 (non Ti, right) and GTX 1050Ti and the 1050Ti is in average more than 2 times faster that the 750.
He got it wrong definetaly,
GTX 750ti is around 50% to 60% the hashpower of 1050ti with similar power usage.
In ex. Equihash: 750ti = 75 sol/s 55W/ 1050ti = 140 sol/s 65W
