I built a small system for my daughter some time ago using an AMD A8-3850 CPU + Gigabyte GA-A75M-UD2H MoBo. She started online gaming so I inserted an R7-260 graphics card, which worked fine. Now she needs to use Autodesk Maya (Rendering/Animation & 3D Modeling) for college and the R7 is struggling. My question, can I insert a later model card such as the RX480 as an incremental upgrade or do I need to bite the bullet here and rebuild.
