confused: how does a videocard relate to my director work environment

["dsdsdsdsd" <webforumsuser@xxxxxxxxxxxxxx>]

hello;

 I am about to buy a laptop and I am discovering that most laptops (affordable)
 have integrated videocards (ex: Intel GMA X3100 w/ 384mb allocated ram
 OR ATI Radeon X1250 w/ 512mb allocated ram );

 I understand that these integrated videocards use the machine's ram via 
'sharing';

 QUESTION: is this an issue for me? I author in director10 with a cast full of 
dozens of scripts, usually one .w3d file ( created in lightwave with somewhere 
between 5000-20000 points ), a flash file that streams in flvs for animated 
textures;


 thanks
 Shannon
