If you can upgrade to a 1050 from the 750 Ti for $10 or less, then yeah I'd do it. First sell the 750 Ti, or try to, in order to make sure you can get as much for it as you think. What dumb person would give you that much for the 750 Ti when for $10 more they could get a 1050? You have to be cold blooded to take advantage of someone like that.
