Graphics Amplifier Purchase Options

So I'm on the screen for the Alienware 13 customization and I want a graphics amplifier to come with it. I clicked the little bubble next to the graphics amplifier option and then it says:

Step 2 (optional): Choose one desktop graphics card to complete your experience.

I need a really good graphics card so I selected the GTX 1070 but I noticed that it removed the bubble from the graphics amplifier option. When I order the laptop will it still come with the graphics amplifier or just the graphics card I purchased? Thanks
