It depends on which model you are talking about,because the 13" model and some 15" models have 9400MGT which is a low-end cards and can play new games at low settings(some older titles on medium).
But some 15" models and the 17" models have 9600MGT which is a midrange card and it can play games at medium settings(some older titles on high)
