Hi all I am thinking of having a system built based on the AMD OPTERON 885 dual core processor using 2 of these and ATI'S crossfire graphics cards (2 of), can anyone tell me which is the best motherboard to get and also which is the most efficient and fastest ram to get as I will be editing video from 6 cameras using premier pro 2.0 and encore dvd 2.0 I have a budget of around £8,000-£10,000. All help is greatly appreciated.

I am hoping to be recording a gig for my friends rock band in early september
I will be using 6 Canon XLH1'S can anyone also tell me if there is equipment that will allow me to switch between cameras and record onto full size DV CASSETTES as the gigs I will be recording are 2 hours long and I dont want to be limited to 1 hour tapes having to swap tapes inbetween. Thanks all
