Ive read that cloning the hard drive is not recommended and its better to do fresh install or migrate the OS. Im debating just putting Win 7 on a ssd and selling the 1 TB on ebay. I actually have Win 7 key and disk. So much easier.
Remember the 650m SLI drivers are completely custom made by Lenovo. You'll need to download or use the installer on the 1TB it came with.
