how accurate is the info given when running sandra? reason that i am asking is that i am getting conflicting info about my mobo. one compaq tech guy told me that i can upgrade to a 2.0 processor, another said that 1.6 is my max(which i currently have) and sandra is telling me i can upgrade 2.3 and above. its a compaq mobo with a intel 845 chipset 478 socket
