i was just wondering if there is a difference in performance for example if i had an amthlon 2600 with 3200 or 3500 memory instead of 2700. Also if there is no difference then that means that 3200 which i think is 400mhz which is in sync with the top amd then wats the pint in the other memory like 3800 surely theres no use for them. Also whats the difference between the different memory standards corsair meant to be good and all but is there really that much differece that its like twice as much. thanx
