Sorry if this is a bit of a noob question but have been following this thread and now understand that the Q45 will have vt-d support and an X3500 graphics engine whereas the G45 will not have vt-d but will have an X3500HD graphics engine. The HD is important for me as part of a home media solution (but would still like vt-d). Does the vt-d support in the Q45 allow vt-d graphics mapping from a dedicated gfx card rather than through the onboard gfx?

Thanks
