Yep,
what is it to be used for?
I suppose that for most users, XP (OS) is the largest memory hog at ~90Mb. (internet & word processing don't need much ram . .you'll be fine)
OTOH; If you want to do video editing or 3-D stuff you'll need a lot more ram.
Just remeber, if that is one of those "E-machines" you will have to upgrade it with "E-Ram"
