The FTW has a 6 pin power connector whereas the SSC does not, which means that it will be able to draw more than 75W of power and therefore will overclock further. If you're not super limited on power, I'd actually get the RX 470 as you can get one for the same price and it will be 30%+ faster than both cards. If you must have the 1050 ti, your choice between the FTW and SSC should be based on how much you plan on overclocking the card. Personally I'd get the SC instead of the SSC as they're limited to the same power requirements anyways and the single fan is more than capable of dissipating 75W, but it's up to you at the end of the day.
