The PC is just used for everyday things like surfing CEG and ClubSi. I'll download short videos and music (when I can get around my school's 3rd Reich-ish firewall

). I have two sticks of 128MB each and my PC operates in pairs of RAM sticks. So another dosage of 512MB (two sticks of 256 each) would fill both banks (four slots). I'm assuming that really would be enough.
