At the moment I'm finding the i7 3930K disappointing, upgrading from an i7 940. I knew that not all software could benefit from the 12 threads but had hoped that the video software I was using which boasted about its support for multi-core rendering (it even has the cpu graphics in the main application window) would be able to use the additional resources. However that one was maxing out at 20%, another I'm trying is barely hitting 30%, I've yet to try the video editing software I normally use but so far the extra cores seem to be wasted. The processor is faster than the older Nehalem processor but I'm starting to think I should have gone with Sandybridge or not upgraded.

I've only had the machine a week though so hoping to be proved wrong.
