Sorry this is a bit late, anyway that's actually a pretty decent (at least compared to my pc) graphics card. Your processor and/or ram might also affect performance though. If you want to see if your computer can run a game before you buy it and install it you should try this website http://www.systemrequirementslab.com/cyri
If you click My Computer details it'll tell you everything you need to know about your computer.
Then just click Can You RUN it? And type in the name of any game. It'll show if you pass or fail the minimum and recommended requirements of the game. If you scroll down it shows all the details, such as the minimum CPU and graphics card compared to yours and whether yours is better or worse. Also a tab for recommended settings. Its free and you don't have to make a profile or anything by the way. And of course if you're having trouble running a game make sure to reduce all the graphics settings until you get a decent frame rate.
Anyway, some low spec games I'd recommend: (free games) Team Fortress 2, just about any free to play MMO, Hearthstone, League of Legends, Spiral Knights, realm of the mad god, Path of Exile (if you're into Diablo type games), and flash games on sites such as newgrounds, kongregate, armor games, etc. Also you can go on Steam and look through the free to play games and check the minimum requirements for anything you're interested in.
Some low spec games you'd have to buy to play: Minecraft, Killing Floor, Super Meat Boy, Bastion, Magicka, Half-life (series), Torchlight 2 (if you're into Diablo type games), and The Binding of Issac.
Those should all run pretty well on your system, but if you wanna play a newer and/or more demanding game and you're not sure if you can run it, just check the website I mentioned and you should get a pretty solid answer.
