Building New FCP System (Please Advise)

I am building a new FCP System on a budget of about 10K. I want the best system that I can build for the money. Mainly I do corporate work such as Marketing, training and corporate communications. I am shooting with Sony F350’s and editing in XD Cam HD and ProRes. One question I have is the graphics card. The rep I spoke with liked the 8800GT. Many systems seem to use the ATI Radeon HD 2600 XT. Is one better that the other for using applications in FC Studio 2. Also, is there a better storage solution than the Caldigit that I have selected? All of your comments will be appreciated.
