I would look into the new GTX 1050 series, they run between 110-165$, if you look at the benchmarks though they are very solid cards, and are probably better than that 730
here is a link you can look at the card and compare it to other cards and look at what fps it gets in certain games

I would shop on newegg.com, and also recommend you go with the 4GB card instead of the 2GB, which is a little underpowered imo
