I would still have to go with what I have seen from several tests. That a 1gigMac equals out to a 1.1Gig Athlon. Though a mac 1gig is 50%faster than a Pentium and an Athlon is about 35%faster or thereabouts.
Look, I have no problems with Macs at all besides the fact that they are not widely accepted and that you CANNOT build your own system unless you frankenstien one together from old parts. I like to build systems; if and when Mac makes it to where you can build your own I would be more than happy to try one out. Until than if I want a DP system I will get a Tyan Tiger MoBo and slap a couple Athlon processors in there and go to town
I would agree with you on Intel though just not at the great rate which you suggest.
