is it possible? are there new gen laptops that let u do so? is there a way to do it at all? (even if it voids ur warranty?) cuz i'm thinking about getting a laptop soon, but i can't find any with a 1gb graphic card. so i was thinkin about gettin one with 512, and mebe in a year or two, upgrading it? i no 512 is more than enough now, but this laptop needs to last me for like 4 years or so :S edit: i found this video http://revver.com/video/377211/how-to-chan...top-video-card/ but it looks rly risky and that definitely voids the warranty lol.
