My Lenovo Thinkpad W530's GPU set-up stinks at Optimus, because all external monitor connectors are hard wired to the NVidia GPU. I need to switch xorg.conf files and restart X to switch between internal and external monitors. Be careful and read the manual before buying and search for the parts about "dos mode" and the GPU. My now left over Asus PL30JT played pretty nice with bumblebee and Gentoo set-up though!
