Define decent? Older games from 5+ years ago should run ok on low settings but modern AAA games are not going to run well on that system. A 750 would be a better choice as the 730 is not really designed for gaming, its for desktop work where the cpu does not have integrated graphics. However 4gb RAM and an i3 2120 are going to stop you running more recent AAA games (last 5 years or more), just too weak.
