Low RAM

Hey. So, uhm. Bottom line? My computer sucks. I have less than a gig of RAM. I'm not very well off in the cash department. I was wondering if there was a good amount of RAM I could buy for a low price, and where I could purchase it. Any help is -much- appreciated.

You're not going to, say, run many simulations with gigabyte-sized data sets no matter how ugly your UI is. The memory used by the operating system is a fucking drop in the ocean compared to what you, the user, will do. Unless your idea of a good time is to play Minesweeper all day long.
