Not sure which path to take. I currently have 1 gig (2 512's) in my mac pro and I can really notice performance drops when using Matlab(I know I know) in parallels, FCP, and especially Aperture. I am on a bit of a budget. Should I get a 2 gig OWC kit and then have 3 gig's, or should I get a 1 gig kit and save $100 bucks and just run 2 gigs for a while. Guess I should probably just bite the bullet, eat cereal for a month and get the 2 gig kit.
