Computer graphics are a broad subject, including but not limited to topics like user interface design, computer animation, 3D modelling and digital art.
One of the most profound impacts of using a base 2 system would likely be on user interface design or more generally anywhere that deals with conveying numerical information, because many layouts including elements that display numbers would have to be changed in order to accommodate significantly more digits. 
Alternatively, the general way of how we display numbers might change much more drastically to save space and/or improve readability, for example by using matrices of colored dots instead of digits.
