That's a pretty good budget and will get you a good video card. You need to list your power supply brand and model and also the case size to get proper suggestions.
For a weaker power supply in the 300 watt range, nVidia 750 Ti, if you have a better power supply, Radeon R7 260X, both are under $160 US and will match the i3 CPU well. I would also suggest upping the RAM to 8 gig for best results if you have a 64 bit operating system installed, since at that price you are looking for performance in games I'm sure. The 260X is generally larger, you can get the 750 Ti in a small form that will fit a compact case, so depending on your setup that may be the best card.
