Many thanks,Risherz.I appreciate your help.Yes, I will call them tomorrow for certain but I am just not sure if I can trust Dell and that's why I asked here.
According to this http://configure.euro.dell.com/dells...rsinspn_1300_1
FSB is 533.
According to this http://www1.euro.dell.com/content/pr...pp1&l=en&s=dhs
FSB is 400.
One more thing-here http://configure.euro.dell.com/dells...rsinspn_1300_1
the price is different from the first link,but everything is exactly the same.
Dell doesn't say anything about USB ports,battery life and so on.
