I have a Dell Dimension 8200. 1.8GHZ P4, 200GB HDD, 256MB PC800 RDRAM. I waited a while to buy more RAM because PC800 is so expensive, about $40 for 128MB. I recently found a good price and am considering buying an addition 256MB. My question is, will I see a big difference in performanec? I have Windows XP Home and all I basically do is Microsoft Office stuff, surf the web, watch videos, listen to music, chat, stuff like that, nothing heavy. Will buying 256MB of RAM make a big difference? When I have Firefox, iTunes and AIM open at the same time, my computer slows down a lot, so I'm thinking thiswill help alot. What do you think? Thanks.
