How good is this laptop for gaming and in general plus will it be able to run mass effect 1 and 2?

I'm also hoping to play other new games on this laptop. I'm not really an expert on PCs so ... Also, would ATI dedicated graphics card be better then nVidia one? 1. ... Thanks Jet. Will I be able to run NWN2, The Witcher and DAO on HP laptop? ... Yes It should run fine and with no problems plus allowance to spare. ...
