I'd recommend getting a graphics card if you plan on doing gaming. Not quite sure but i'd assume you would get around 30 fps on games from 2013 or 2014. Don't expect to be playing star wars battlefront or fallout 4. You'll definitely be able to play CSGO at 60 fps, I'm not sure at what resolution or what effects you can have on.
Overall its a good computer. If you're doing light gaming you might want to go with 4GB of ram and upgrade if you plan on doing heavy gaming.
