i got a ati xpress 200m intergrated video card on my laptop can i upgrade to something a little stronger is that possible on my lap top its a gateway mx6440

Video Integrated Radeon? X300 based graphics it says i have is that good for the new ubuntu 7.04 and the effects with out to much difficulty and run smoothly have not been on in a while

I doubt that laptop has a slot for a new card. Some Dell's do but upgrading them can be a little bit of a task and normally more expensive then it's worth.
