Ok, I just took on a webmaster job part time for my school, and I'm going to be using Photoshop,Dreamweaver and Flash probably simultainuously. I have a stock iBook right now. Question is is another 512 MB going to be sufficient to run 2 of those programs at a time or do I really need to go upto 1024? Money is tight and saving anything would be good but I want my comp to run smooth and not have beachballs when I'm doing the job.
