Hi, I've finally decided to purchase a Mac so that I can do work from home. Just a few questions, any responses would be a great help. What I know I want: G5 dual 2.5 atleast 2 gigs RAM atleast 250 gig HD 23 Inch Apple HD LCD monitor 1.) I will be running typical GD software along with some film editing software and Maya. What is the reccomended amount of RAM so things run smoothly? Also, I've noticed people recommend buying third party RAM on these forums. Is this a good idea? Any particular brands and configurations? 2.) Which graphics card should I go with ATI 9800XT or Nvidea 6800 Ultra DDL? 3.) Should I wait for the next generation of Macs to come out? Being my first Mac purchase, I really want something nice so I'm looking to spend between $5,000-$6,000. Thanks in advance.
