I am looking into purchasing a new graphics card for my Notebook, it's a Dell Inspiron E1405. I want one that can at least handle higher end PC games, so I don't have to turn every graphical setting to "low", problem is, the E1405 is an extremely mobile laptop and I am not sure what graphic cards would even fit in my notebook. I am looking into nVidia or ATI (I don't even know i there is another major video card supplier). Can somebody please help me figure out what cards would be compatible and fit inside my notebook? Thanks for any help.
