Okay, I am a professional graphic artist and a 3D modeler. I use CS3, Painter, Zbrush, Maya, Modo on a daily basis. I have been using my 2x2.66 w/5gb ram at work for the last year and my powerbook g4 for the last 3 years at home. My work system can slow down and my PB is way too slow for large files or high poly counts. I want the new MP to last me for the next 5 years. I have learned from this board and from personal experience that I should buy 3rd party ram, but from there I cannot decide other factors. The questions I have are: Should I go with 3.2 or will 3.0 be fine? I'll have 16gb of memory, but is the extra processing speed worth it? Will the 8800gt be good enough or should I be thinking about getting the Quadro? I am getting conflicting advice on the apple HD's v. 3rd party HD's? RAID or no RAID? Thanks all, anything to help my spinning head will be much appreciated!
