SiSoft was definitely one of those applications to really take full advantage of the extra computing power of the Core i7-980X.  In our CPU arithmetic tests it scales just about perfectly getting a 50% higher score in both results.  The same is seen in our integer, floating point and double precision testing on the multimedia benchmark.  The rest of the tests saw either minor (by comparison) performance gains (multi-core efficiency, cache and memory) or none at all (memory bandwidth, latency) which falls exactly where we expected it too.
