Exporting the Windows Task Manager Process List

I'm trying to make a case for a new computer at work. One of the things I want to show (besides the incredibly slow boot time) is that I am maxing out my RAM. To do that, I wanted to get a list of tasks running that I could import into a spreadsheet to figure out how how much memory my day-to-day applications consume (Outlook, Eclipse, SQL Developer, Firefox, etc.) versus all of those background processes that I don't even know what they do. Here's how I did it:

Start -> Run -> cmd
tasklist > tasklist.txt

Then open tasklist.txt in Excel as a fixed-width file and go to work.
