From the FIRST paragraph in that article:

When you install Exchange Server 2003 on a Microsoft Windows Server 2003-based computer that has 1 gigabyte (GB) or more of physical random access memory (RAM) installed, and that is home to mailboxes or public folders, you must edit the Boot.ini file to optimize the virtual memory usage of the Information Store service.

/3GB is very confusing. Leew is right. It's very important to use this switch since otherwise you may get memory fragmentation.
However, you should also use the /userva switch as per http://support.microsoft.com/kb/815372/en-us
Quote from the article: "If you are running Exchange 2003 on a Windows Server 2003-based computer, and if the /3GB switch is set, we recommend that you set the /USERVA=3030 parameter in the Boot.ini file."

Your best option is to run the Exchange Best Practises tool from Microsoft (free download). That will tell you if you need to use it or not.
