Only problem is optimus....I'd love to run linux on it but optimus sure sounds like hell brought to earth.

Anyone know if the BIOS allows the disabling of optimus and if the internal screen has a direct connection to the nvidia card instead of being muxed by the iGPU?
Not sure if you can disable Optimus in BIOS - you can easily set it so the discrete GPU is always used, worst-case. Perhaps you should look at the Nvidia Optimus whitesheet (
http://www.nvidia.com/object/LO_optimus_whitepapers.html ) - by definition the display output gets sent from Intel HD graphics on all Optimus systems. Making 2 paths would defeat the purpose of Optimus as switching wouldn't be instantaneous, and HD 4000 easily has enough bandwidth to handle a 650M.
*Note on the Optimus whitesheet, the good stuff is roughly from p. 8-15, skim that for Nvidia's old graphics switching technology, and around p 11 it gets to how Optimus works.
