Sorry, Jabba10. It can't be done. The best you can do is get the latest driver, but that will only increase performance a small amount, if at all. Notebooks do not have expansion slots. Normally all you can do is add RAM, though you can buy and fit replacement drives (hard and DVD). With some, you may be able to fit a faster processor.
Some of the very newest laptops have replaceable graphics chips, but I don't know whether the replacement chips are available yet - these are usually the newest nVidia and Ati chips only.
