I have a new 3.0 mac pro on order with the the 8800 that will be set up as a FCP HD Edit station and After Effects Graphics station. By the time I get everything I need (raid card, capture card, new 30" ACD) I'm into the system for about $10K. To get 16GB of Ram (from OWC), I can buy either the 8x2GB kit or the 4x4GB kit (which I can always upgrade later with another 4x4GB when the price comes down). The 8x2GB seems like it would be faster in the near term (according to Bearfeats) but am I sacrificing my long term upgradability to save about $600? And would 16GB of Ram be enough? My current machine is a Dual 2 Ghz G5 so the new machine will blow it out of the water regardless.
