right now I have a 40gb harddrive. it is basically filled up all the time, with about 200MB free. I have 5 users on windows xp pro and about 3 are logged on all the time. i have 256mb of ram so my computer can get pretty slow. i want to speed it up, but I don't have much money to spend. I can get a 80GB harddrive and run that along with the 40GB drive I have now. I can get the 80GB drive for around $55. Or I could buy more RAM. I really don't want to because the only RAM my dell supports is expensive (pc800 rdram), about $45 for a 128MB stick. If I get the bigger harddrive, would it make a big difference in speed since there will be so much extra room? I don't have a good paying job, so should I just get the harddrive now, or save up for awhile and get about 512MB of ram?
