Yo. I totaly aggree with Emmanuel. Number of cores is the main factor for rendering. If you need good gaming laptop then prefer ATI radeon as your GPU. Because its perfomance speed is too good(not Quality)and less price than Nvidia. Size of RAM memory(both GPU and physical) is an another factor for perfomance. Also I want to tell you that the monitor which have 15" size or more have numeric pad(numpad like common desktop keyboard).
