They need to go. Unless you are going to use the Virtu MVP in multi-monitor mode, which wouldn't make sense with your high performance vga card setup. The HD4000 drivers will otherwise conflict with the Nvidia drivers. The only way (that I know of) to make both work together is to use the Intel Display drivers suppliled by Asus on the DVD, not Intel's. You can use the Intel drivers if you want, but then you have to remove the Nvidia cards and drivers.
