well, while it is that DirectX's console app will give you a fair amount of information on your PC, it will give so much an no more.
Typically it gives your CPU speed, and the amount of RAM you have in your PC, as well as the type of graphics card you have.
But if you really need more detailed information about the specs of your machine...
such as the MODEL RAM you have, its speed(s), the type and details of your motherboard, details of your CPU such as its speed in mhz and its cache size. Core voltage of your CPU... such DEFINED details..
you should use a sys info tool like :
