Will my Graphics Card fit in my Desktop Case? (Width-wise)

My case is pretty narrow, and the Graphics card I want is pretty damn big. The thickness of the card as well as the length of it is fine and will definitely fit in my case, but I'm a bit worried about the width of it.

Without the Motherboard, the case is 16cm wide. With the motherboard, the width of the space is somewhere between 14.5 and 15cm. The card itself is 14cm wide which would leave a gap of approximately 0.5 and 1cm.

Will the card fit?
