I was thinking two sticks of 256MB as that seems to be about the cheapest way to get max memory right now. I don't know what operating system you are running but I don't think you can address more than 512MB with Windows. Maybe with Windows XP, but that's a week away {g}. I haven't looked at this in a while and I could be a processor limitation rather than the OS.

By the way, Microsoft is doing the live satellite TV thing for the Windows XP rollout this weekend. There are theatres all around the country you can go to and watch Bill and his team talk about the latest and greatest out of Redmond. It's free, and you usually get some freebies when you attend as well, like t-shirts and mousepads. Sign up on line at the Microsoft site.
