I was looking through the used listings in my area and found a mac pro with the following specs: 8 core 2.8 2 GB RAM 1 TB drive Geforce GT 8800 512MB 2 x DVD drives Seller is asking $2800 Is this reasonable and is there anything I should be checking? Is it worth getting this system over waiting for Nehalem chip sets? I edit video on the side and would like to dramatically reduce render times over my 2.16 macbook. If I buy the system, what kind of render improvements can I expect? For example, I occasionally use a flash based camera that stores HD files in mp4 format. The macbook can take 2-3 times longer to render a clip than the clip duration. Thanks for any direction. It's not my first Mac, but it is my first Mac Pro.
