the x2 just meants its a dual core.. and for an amd x2 3800 2ghz is what its supposed to be clocked at .. there is nothing wrong with your cpu.. you can't compare the speeds of amd's to intels... amd can push a lot more info with less speed.. there cpus run more efficiently thats why a 3800 compares to an intel 3.8ish (not really but thats why they call it that)
