Sorry, yes, you are right. My current 2.8GHz i7 runs the benchmark very 
slightly faster, in 1:47:07. Not bad you might think, given the slower 
clock speed. But my previous box - a 2.2GHz Athlon X2 - is still the 
quickest, at 1:42:30. That record was also set in 2005.

AMD make good chips... why did I buy Intel this time I'm asking myself?!

Very interested to see what a new Phenom will do. Might get near the 
hour mark if it's as good as my old X2, cycle-for-cycle.
