H67 MB + IGPU + Nvidia, possible?

[jbuttah]

I read the SB cpu review here on Anandtech, and in the section dealing with QuickSync, the review said it's possible to use a discrete GPU with the IGPU if you have a monitor connected to both. I called Asus and they said their MBs automatically disconnects the IGPU if it detects a discrete GPU. Anyone know if there are other MBs that allow this?
