I got the average of 9%(including that large improvement in one test-sse4) looking at that exact review,~7% without that one.

If you use that logic, including Minesweeper, Calculator, Wordpad, Firefox for "overall" performance, K8 would be equivalent to P4. http://www.anandtech.com/cpuchipsets...spx?i=3038&p=8 Or that "on average", A 3GHz dualie is just 3.7% worse than a 2.4GHz quad. Good thing for weighted averages, ignoring of pointless benches, individual workloads

The "minor" improvement of 100%+ in encoding and 10-30% in gaming is going to be quite appreciated I thunk.
