Actually, my company has wrote an CUDA application for 3D used with GTX 275 2GB that is now discontinued. Anything with less than 2GB would not qualify. As a buyer/planner, I need to tell them the reason why we don't actually need 2GB with modern GPU. They kept throw me under the bus. So, I need a lot of the technical information to present to my boss so I can purchase a new video card to run our application without the need f 2GB memory.
