Wow, we do have the same sys. I am having some second thoughts about the accuracy of the task manager performance mon. Do you have trouble with DVD playback? That is really the only place I see the performance struggle.
dev studio is a programming environ, and I dont think it puts anything in.
I am more likely to reinstall win 2k and keep a closer eye on the performance after I get the geforce mx card I have had my eye on,
