That's not a very good card. The 128 bit bus on the GT730 only supports 2 GB RAM, and DDR3 will be very slow. The 64 bit 1GB DDR5 version is the best. But if you already have it then yes it should work.
i would have gone with a 750Ti low profile just to be safe the 730 is at the bottom of the barrel as far as gpu's are concerned
