Physics & Computer Science

My dad and my physics teacher have (independently) advised me, as a CS major, to minor or double-major, in physics.

Do you think this will really help me get ahead? I want to end up doing something with computer/video games, not writing scientific software, so I think basic general college physics (required for CS major already) is enough.

If you want to get a head, surely biology would be more suitable. unless you want like a robot head.
