I plan on buying the new MacPro with Two 3.0GHz Quad-Core Intel Xeon (8-core) I want to know how much RAM I would need if I have these apps: Photoshop cs3 Illustrator cs3 Logic Studio Final Cut Express Office 2008 Pro Tools I'm probably gonna get the NVIDIA GeForce 8800 GT 512MB also. I will obviously be recording music and editing movies. Would 4GB of RAM be sufficient? Would apps work smooth enough? This is quite the investment, and I want to do it right. I appreciate anyone with info / suggestions.
