Hi tag1_uk. This is my opinion - others with more experience may differ. I don't think changing your graphics card will make any difference for your requirements, the new super powerful cards are aimed at gamers who want high speed rendering of moving 3D images. Changing your processor from a 1.2G to 2.4G (effective) will give some improvement if you are manipulating large graphics files, and increasing your RAM from 384M to something like 1G will help with complex tasks under Windows XP. If you get a new powerful motherboard you will almost certainly have to get DDR RAM anyway. I don't think any of the changes will make much difference for large text documents. In my experience what will help most there will be to break the large text documents into a number of smaller documents. Also make sure that you have plenty of spare hard drive space and keep the hard drive defragged. Also make sure that all your vital files are securely backed up (preferably with 2 copies of each file on cd - just in case).
