that should be ok then, as far as the nics.  As far as the scsi drives, 
I am moving them along with the controller, so that should be no 
problem.  In your opinion, should I wait to see if the extra memory 
solves the issues or jump straight to the new mb and memory.  old 
machine is hyperthreading 3.06 with 2 GB ram, and I have ordered memory 
to go up to 4 G ram.

if I have to, I will go to a real dual cpu board
