i'm just wondering which TiBook to get. i'll be using stuff like Photoshop, flash, illustrator etc. i'll also be doing a fair bit of 3D work as well, Maya, cinema 4D etc. the 667MHz TiBook with 1GB RAM and 800MHz with 512MB RAM are my options, i've managed to narrow it down that much. so should i speed for RAM and get the 667MHz or is speed more important? thanks for your help.
