Hey, I have a Titanium PowerBook 400MHZ with 384 MB RAM. Realistically, would most of you guys recommend upgrading my RAM in terms of spped increases etcetera. Programs which I usually run concurrently include Xcode (also gcc cpp, etc), Safari, Microsoft Word, and iTunes. I'd like to see an increase in speed when compiling, when using update_prebinding, in startup times, and when switiching between applications. Will I see this when upgrading to 512 MB RAM? To an even greater extent when upgrading to 1 GB RAM? Or are executables such as update_prebinding simply reliant upon processor speed? Thanks, Cheers!
