Thanks for the responses guys, it seems that any dual core clocked below 
2.5ghz (AMD or Intel) just isn't enough.
How much optimizing room is there left in the h264 code?  If there isn't 
much, Am I better off with a AMD x2 5600/6000 or a X3 8450 triple core?
i.e. how well does h264 scale across cores on a lower clocked CPU?
