I once went for lower CAS timing 2x 128MB ram sticks (256 MB) instead of 2x 256s with slower speeds because I thought 512MB was insane overkill. Realized how wrong I was when trying to play Star Wars galaxies mmorpg when a lot of people were on the screen it started swapping to disk. Look up the specs for an IBM Aptiva, first computer my parents bought, and you’ll understand how 512MB can seem like a lot.
