Taylor: Avoiding Jitter in Composited Frame Display

one thing to remember is that dedicated video cards tend to have higher memory bandwidth to their dedicated memory than the system does to it's main memory (they need far less of it, so it's affordable)

the display framebuffer only needs to be a few 10s of MB of ram. So the 3d TV units may display at 120 or 240 Hz, but they receive their input at a much lower rate, just storing two copies of each frame to alternate between.
