>Powermac 1 Ghz has faster memory access and is faster as a Peg2 .. but I don't think it's that a big difference.
The Powermac also has a true AGP 4x slot which might make some video card operations faster.Hi,
Quicksilver have 1x UDMA66 and 1x UDMA33 IDE ports - Pegasos2 have 2x UDMA100 IDE ports.
I tested same HD on these machines and it's really slowly on quicksilver.
