If anything you should be seeing how far you can undervolt this. You're working with with a 150w Battery as a power supply. You need to lwoer your expectations and get used to gaming at medium settings @ 720p unless your willing to upgrade.
A 960m is basically a 750 with no gddr5 iirc.
Im pretty sure I posted this in your other thread you made.
