Odd idea. I wonder how folk know why this is overkill for 99.99% of us.
2 GB would be at the extreme end and not necessary. i also like to get a lot of years out of my desktops by getting lots of memory. I have been using a desktop from 2004 until recently because I got it with, at the time, overkill ram and video. I also do game from time to time, especially the Total War series with large unit numbers, which eats up memory.
