Greetings. No computer guru...just your regular user. Appreciate your input on these questions/concerns: 1. Is upgrade worth it? I normally run MS Office and a few non-PC games (Vegas 1-2, other Clancy, etc.), mostly. Hardware is HP quad with 6 gig RAM and 512 mb video card. Can I just run the upgrade w/out having to reinstall all my other software? 2. Will I see noticeable performance/speed improvement? I think 32x settings limit RAM use to 3 megs....and I typically have several programs/files open at once. I have the Vista 64x program...just wondering if I should install it. Thanks!
