Not sure of your budget, but a GTX 1050 (2GB) and GTX 1050 ti (4GB) are better cards and not particularly expensive. Can't get GTX 750s without going to 2nd hand ones here.
If you have your heart set on the 750, read reviews on benchmarks vs noise and wattage, take into account the ports on each, the length of each, and decide based on your personal requirements.
Edit: Compare GTX 750 Ti with others
