    the only way I can think is looking at Performance Monitor (you can open it from the performance tab of Task Manager).
    You see CPU load with the cards doing nothing, then you look at total load when the cards are doing something.

    Frankly, modern CPUs aren't so bothered by PCI as the PCI standard was designed with far far crappier (older) CPUs in mind.
