Well the centrino to my knowledge has no or a reduced performance math coprocesser. This is bad because graphics applications particularly 3D graphics apps rely heavily on that. Personally I perfer AMD processers they tend to be a bit better at the math co processer in the past. (I have not kept up to date on this) Get a good graphics card in the computer the best you can get helps with the games a lot and a bit with the 3D graphics. The problem with laptops is often the centrino style processer coupled with the weaker than normal graphics card.
