100MB is a pittance of what memory we see installed in today's machines. My old desktop has 1GB RAM and that .1GB file shouldn't ding it at all. So that's not it.
Is this old PC fitted with some video card from that era? That's the most common reason I see for sluggish behavior.

Will the mac octo-core be overkill to run Adobe CS2, later CS3, and Corel Painter 9, later 10. I have a 6 year old PC that runs annoyingly slow on a 100MB file, and want to switch to the new mac Pro, but should I wait or buy now? rumored release Feb 20th, but could be later (June)
