well we were talking Dual AMD proc. You get what you pay for is not so true in computer components especially pc parts. I'm running a 1.4Ghz Athlon with 512mb ram that I threw together for less than $250. Had I thrown together a Pentium 4 I'd be sitting at 1Ghz with Intels crap floating point causing me performance issues. On the other hand I would have spent over a grand for a similar Mac system. Shoot you can pick up a 1Ghz+ AMD system from Dell with full tech support and monitor included for less than a grand. Throw that up against a $2500 G4 and we come out about the same. Mac floating point is good but not so good to out perform a 1.2Ghz AMD on a price bases.
