Xeons are workstation/server processors. They can be used in uni or multi processor systems. You can in fact run just one. Random google seach on "xeon" and "workstation" brings up: http://www.hp.com/workstations/products/winnt/x4000/summary.html As you can see you can happily run it as a single or dual processor system... And as for why one instead of two... true I'd rather have a single 2.8 GHz processor instead of dual 1.4's. But price is a consideration. One 2.8 GHz Processor = $470 on pricewatch.com. Two P4 1.4 GHz processors = $278. But then again, if money isn't a concern I'd rather have dual 2.8 GHz processors. Or I'd just wait to see if I could get dual 3.06 GHz processors hooked up on or after October 25th. 6.12 GHz... wouldn't that be sweet.
