The Radeon 7520G is an integrated card. Therefore, older games and graphically non-demanding games should work. Just don't expect to run them at Ultra settings. For instance, WoW would run well on medium at most (preferably low).
For "light" gaming (emphasis on light), it should be adequate.
If you can find a similarly priced laptop with a GT 630m or 635m, you should go for it!
