Anyone know a scale of how much memory you need for certain activities? For example, 1gb of RAM is not required for a person who just uses his/her computer to surf the net and write letters. On the other hand someone who does heavy video editing might need +2gb of ram. In my situation I'll be doing light gaming (CS:S and HL2), sound mixing and editing, web page editing, and everyday web surfing and word processing. Do I need any more than 1gb of RAM? I'm asking this partially because my mobo only has two DDR slots. If I buy two 512mb sticks, I doubt I'll be upgrading later on since my mobo is s754. If I get 1gb (more pricey) then theres always the possibility that I can add an additional 1gb later on. However I don't see myself needing that much since I doubt I'll be getting into any real heavy gaming/video editing.
