Hello i just bought a dell inspiron 9300 laptop and i already need to upgrade it, a surprise i know, haha. Anyways it has a 128mb Ati mobility x300 graphics card which is the bottom of ATI's line of notebook graphics card. I want to upgrade the video card, im pretty sure it might be more involving then upgrading the RAM. My question is is there a manual online or some online resource you could direct me to with instruction on how to change out the video card in a notebook. I also need to know a place when i can purchase graphic cards for notebooks because im having trouble finding a retailer. thanks in advance for your help.
