Why don't you get a 1050 or a 1060? It's new and it's cheap. Just make sure you have ewnough power and everything.
Hop on PCParts picker and spec out your computer to get a somewhat accurate idea of the power your pulling now.
The 760 is an okay card, my buddy has the 760 but you might as well just go pascal for the price.
If you do get the 730 just don't expect it to do to much.
