At work, they just upgraded my machine from 512 MB to a full 1 GB of RAM. Man, what a difference. I can actually have Outlook, Visual Studio, Enterprise Manager, Query Analyzer, Clear Case, TestTrack Pro, and IE all open simultaneously and not suffer any performance degradation. Before, if I wanted to have more than one instance of VS open at a time, I had to close everything else, including Outlook.
Ah, life is good again.
