I have 512Mb's of 400MHz RAM, but I seem to run low on it once in a while. A few days ago my system was lagging as heck, and I couldn't find what process was doing it. Probably a spyware problem though...
Anyway, while running Photoshop 7, Winamp and Firefox, you should be fine to pop up MSN as well. Unless you're using <256Mb of course.
