how Oscilloscope Cards transfer sampled data for display on PC

Hi everyone,
Most of oscilloscope cards and DAQ cards have very high sample rate in comparison with the speed of thier interface port (for example usb).
I know that it is not necessary to send all sampled data to pc for display and most of digital processings are performed by card itself.
My question is that what is the best rate of waveform display on pc and how is it performed exactly?
Thank you in advance for your comments
