My laptop blew up and the company I bought it through is going to replace it with a newer model (old one doesn't exist). When I bought my origional laptop the X700 was top of the line. They want to give me a machine with an X1400 in it. Does anyone know if this will out perform my old card. Also, I notice there is an X1800 mobility chip on the market so the X1400 seems to be low performance?
