i'm going to buy a notebook, toshiba brand. currently doing some study on that. Meanwhile i also going to replace my older graphic card. i found out the difference between Nvidia Geforce 7series and Geforce 8 series, made a comparation on GForce7800 and GForce8600 GT, they're much different on performance. 7800's performance such as memory bandwidth was higher than 8600, i though the latest version will be on higher performance,isn't. and i'm wondering that the performance of the notebook's graphic card is same as PC's graphic card. that's what i hesitating on. Could anyone give comment.
