Goes like this. 1050 is pretty powerful. Say its strength is 40x. But when paired with that processor, it will perform something like 30x, and not 40x. On the other hand, a card like 750ti, whose total strength is upto 30x, will perform 30x when paired with that cpu. But the flip side is, if you choose the 1050, there is an advantage that you can take it to your next build, should you choose to do so.
Not sure whats your location, but both 1050 and 750ti might be in the same price range.
So those are the facts in a nutshell, now its your call.
Hope this helps.
