That's not correct. Since 2001, the NSA has been retasked to recording all SIGINT information, and figure out what's relevant later. This was the reasoning behind NSA Total Information Awareness (hence the name,) as well as its successor programs including PRISM, FAIRVIEW, MARINA, BASKETBALL, etc. Also, if you want an undectable CPU monitor, just use a temperature sensor strapped to the processor. Temp-monitoring was even used to find TOR hidden services.
