Thanks for the detailed reply!
This answers my integrated GPU overclock question and gets at what I was trying to figure out for the other.
Looking at the article with the flow diagram, it seems that they are running a 2 monitor setup but both display cables are coming from the motherboard's ports. I was thinking that one cable could be directly to the GPU and the other to the motherboard port, but it looks like to be able to use the Discrete + Integrated GPUs with Lucid Virtu requires it to be centralized through the motherboard ports. I guess they haven't shown tests with both GPU/motherboard ports being used because the software doesn't allow it.
The point of this dual GPU setup for me was to have my discrete GPU use most of its processing power without being hampered by the 2nd monitor. Seeing the ability to be able to specifically choose applications to run on the discrete GPU puts my concerns aside where (hopefully) any application other than the full-screened game I would subsequently run will be allotted to the integrated GPU's renderer as the point of Lucid Virtu is to simultaneously use the discrete and integrated GPU, since the discrete GPU would be (heavily) in use already.
A small side question is to the HD Graphics 3000's performance: Can it run smoothly 720p video, streamed and/or downloaded? 1080p?
Again, thank you for your reply.
(Will probably Best Answer after seeing what others, if any, have to say.)
*Just saw you replied while I was typing this, so I guess we both saw that the "whitelisting" would basically solve the main issue of maximizing the performance on a demanding application, while the integrated GPU would do any other rendering.
