Virtu MVP utilizes the intergrated gpu on intel processors and the dedicated gpu that you choose to install. It is limited to specific games that Virtu MVP has support for but seemed to ok with the games I tested. I personally uninstalled it since my gtx670 already runs those games at 60+ fps and don't consider it important.
Its ok, When i used it it did work pretty well, the adaptive V-Sync was nice and the Hyperperformance gave me about a 5% boost an my average framerate (so at 60 fps about 3 FPS) that being said its definitley not necessary.
Id go with the D3H out of that list of motherboads though, Gigbayte has a really solid lineup this gen for Intel.
the idea of it is cool, but the implementation is kind of sucky and gimmicky. if it could remove the load of OS based graphics so your dedicated GPU would only have to deal with game graphics, then it would be cool stuff but that's not the case. so it's not really a selling point.
Came with my motherboard and when I went to boot up my games they would become pixelated so badly I could barely make out the main menu, wouldn't recommend it to anyone they have a list of games that "support" it but I found at least 4 that didn't.
