The Quadro's are designed for dealing with rendering and CAD programs, whereas the GTX series were designed for gaming. A multi-monitor setup would benefit greatly from the 970 compared to the k2000m, but it depends. Also do you mean 970m? as the normal 970 is desktop, unlike the other GPUS listed. I would recommend the 970 for better preformance in gaming, but we need context. Are you replacing a Laptop GPU, building a desktop and you thought the kxxxxm series was dektop?, Provide answers so we can help you better.
