xBench of a new iMac 1.25 GHz

Thanks to Benoit for sending us his xBench results of a brand new iMac 1.25GHz (delivered in the US)

Overall, this computer seems really fast.
However, the User Interface test remains too low. Why is Apple always releasing a powerful computer and finally decide to limit its performance by incorporating a G4 without L3 cache?? We all know since the MDD series, that 167MHw bus with a G4 processor is more impressive on the paper than once used....
