I use a couple systems at work with 64bit, and this seems to have very little ram for a 64bit system. The whole point of 64bit is so that you have more memory. If that memory is paged, then not only do you have larger addresses and more bits (for every calculation), you are accessing it via your harddrive.
I'm not a computer guru. So please if this is wrong, correct me and set the internet back on the right path.
