That DDR3 730 is a really low-end card. It's going to struggle for any sort of demanding gaming. If all you want is League of Legends or something, it'll do the job, but it's low end.
What's your budget? Even the 64bit GDDR5 version of the 730 is a much better card and often costs a similar price. It'll only have 1GB RAM, but don't be fooled, it's significantly faster than the 2GB DDR3 version. Nvidia should be ashamed of themselves for releasing multiple GT 730 cards (there are actually 3).
