Give ntune a try:

That's Nvidia's monitoring system. I'm not sure if it'll monitor your 3870X2, but it should still at least monitor your NB. Just instal it, open the app., let it start, and click the little arrow at the bottom right-hand corner. You will see a graph, and two readings above it, one for your chipsed and GPU.
