Hello,
As I understand you have a system that features Intel® HD Graphics and you would like to know if you can add a discrete or add in PCI Express* video card into the same computer and use them both.
This is a new feature that is called switchable graphics and this depends on the implementation that has been done by your motherboard or computer manufacturer.
In this case we suggest you to contact them directly to see if this would be supported by your system.
