Re: nVidia Optimus Questions
There's Bumblebee, which is a sorta solution for Optimus. But yeah, if you can in any way, try to get a non-Optimus laptop. A lot of Asus models provide a hardware mux, which allows graphic card switching, so you can switch between Intel/Nvidia/Optimus.
And a little something I hear, but I don't have fully verified - the dual graphics situation on the other side (AMD) is also quite a pain. So if you can, get a laptop with Nvidia but with a hardware mux. If that's not possible, you can get by with Bumblebee.
