I'm currently using PE2, and I'm thinking about switching to PE7. Anyone running PE7 with XP? I'm only running 1gb of RAM on a 3 year old notebook. PE2 is working fine for me, but am curious about the newest version.
It's hard to say without knowing all of your computer specs. But, if you can run version 2, you'll likely not have any problems running version 7 (assuming you're not going to suddenly start editing HDV).
Version 7 does tend to use a little more memory though. So you may want to look into bringing your RAM load up to 1.5 or 2 gig, per the version 7 FAQs at the top of this forum.
