Hi Frank,
Congratulations on getting your hands on such new technology and at a good price. I have questions of my own regarding the dual processor machines.
All of the consumer dual processor machines I have seen seem to be running really slow CPU's like your 1 GHz processor. Why is this when 2 or 3 GHz processors are available rather cheep. To me more is better. Maybe it doesn't work that way.
The other concern is I think only certain programs can take advantage of the extra power the dual processors provide. I guess I'll have to do some more reading on this.
Good luck and I'll be watching this thread. I am using an SDR 1000 and I have seen others on the Flex reflector that use duals. Your SDR projects are probably different as you don't care for the 1K. You might try the flex reflector.
