I am about to purchase and setup a SBS 2003. Just wondering if there is any problems with starting off with 1 processor (on a dual capable board) and then adding a second processor down the track if need be? In other words, SBS runs for 6 months with 1 processor and then wakes up one morning with 2, would it have any problems? Or am i better spending the extra $$$ now and starting with 2? btw the processors will probably be Intel 5130's (although i'm open to suggestions on that too).
