my powermac g5 (dual 2.0) benches 1829 in geekbench, wich isn't bad (i think), but my late 2006 macbook benches 2712. they both run osx 10.5.8 and both have 3gb ram. i don't know if my g5 is broken or what but with the size and the power consumption, i don't know why it's so slow compared to the macbook.
