I am mining Eth with 12 x 1050ti, 180MH/s. Estimated earnings from ethermine are 277$ a month, January i was earning 700$. So i think they are good mining cards, the difficulty on ether constantly increases, so i don`t know what will happen in the future.
Same for me. Plus the added benefit of very low power usage compared to 1060's & 1070's
