Just as an FYI, just swapping that chip won't turn a non-GT Complete into a GT Complete. There is a security chip on the board someplace that has to coincide with the U53 chip. And the Upgrade disks, which are used to upgrade from an older to the complete version (and update the security chip) require a call to IT to complete, but the number no longer works. I don't know if anyone has found a way around this yet.
