So how much does it cost just for the CPUs themselves and nothing else? I'm guessing maybe $1000 for the pair? Just remember that the Sams come with only a single PPC whereas the X1000 comes as a pair thus explaining such a high cost... 
oh dear. :insane:
Its just the one CPU, that feature two cores.
Its been said that the CPU chips cost $500 (£400) each, now add the Xmos and few other things on the board, in actually cost I'm guess it cost no more than £600 to make a X1000, but then you got add cost of developing the board and cost of porting OS4 and Linux to the machine and all the extras like Ram, Gfx card, HD, DVD drive, Case, PSU, Cables, Taxs, Profit margins, Packaging, Shipment cost, etc and it soon get to £1,500+.
