if all I was to do all day long was run photoshop, then the G4 would certainly be tempting

Indeed. Why? Because for all of those tasks where performance is processor-bound, Photoshop has been AltiVec-accelerated. The same is true for Final Cut Pro. If you edit video for a living, a $3K Macintosh with FCP will kick the pants off of any Windows hardware/software combination. That's why FCP sells more than any other NLE. It works flawlessly with multiple G4 processors, and uses AltiVec on both processors to render real-time effects.

But guess what? Core Graphics is extensively multithreaded, MP aware, and AltiVec-accelerated too, so the window compositing used by Mac OS X is much faster than any P4.

But there are still some people whose work has not been well accelerated by AltiVec or MP. Who? Mostly people who run test suites for Wintel magazines. If what you do all day is run benchmark software on a single processor, then you want an Athlon. Macintosh is just not well designed for running benchmarks. But that's okay for the rest of us.

Bottom line is 866Mhz G4 is about as fast as a 1.45Ghz P4.

According to the latest figures released by Apple, even that might be too optimistic. They are proudly announcing that a dual 1 Ghz G4 beats a single processor 2.2Ghz box...
