Any idea which one of these would be faster?

Thanks I had found other benchmark sites too, but that one is great because it has both the QS and the MDD G4 dual's on it for comparison.

I'm trying to sell my G5 and the person who wants to buy is also consdering another computer but it's a dual 1.0ghz G4. I thought for sure the G5 was faster overall.
