Hello LJ, It would help to know what type of signal processing you are hoping to do and how you want to display or save the data. On generally available consumer hardware GNU Radio has been shown to be able to handle 800+MS/s of samples being displayed in spectrum plots.
It sounds like you are trying to route too much data to your speakers. Are you able to share your flowgraph? There is a screenshot function in the menu or the grc file could be attached.
