Slow and old, but I don't do a lot of PS work. Much of the time I'm converting videos for DVDs. Yes that, too, is slow but I can set to work and walk away.
Do you use Handbrake? If you do, how many FPS does your G4 gets when converting a DVD to iPod Hi-Rez?

...Mac Pro is good for multi threaded applications since it has 8 cores and basically, it is the cheapest workstation in the market, even against you building your own workstation!
I'm anxiously waiting to see if there's any speed up on the mac pro. I'd also like to see how fast CS4 Leopard compares with Vista64. Somebody please do all the tests, especially the one on driverheaven:

Exman,
I did notice your revealing tests. I assume the CS3 tests were done as fairly as possible--the same number of history states, ram allocation, scratch disks, etc.?
I think this all boils down to Adobe spending more time and resources on optimizing PS for Windows. Also all video drivers are better optimized on Windows. I don't think we will see the Mac getting even or surpassing until Snow Leopard, Nehelem processors and CS5 which will be in Cocoa and 64-bit. Still, it must say something about the speed of the OS if handbrake is slower on OSX as well. What do you think accounts for the speed difference? I suspect that intel chips are always optimized for windows code or intel shares a lot more proprietary info with Microsoft.
I am interested to see if any of the Open GL stuff can improve performance in PSCS4 on the mac, though I suspect it mostly improves display zooming. But it might also benefit certain photoshop operations.
I still await CS4 speed tests. My guess is that CS4 is at best 10% faster than CS3 on the mac with the same hardware. Adobe has not advertised any kind of improved performance, so I'm guessing there ain't much or it's a wash, the new features aside.

sneezymarble,
.S. I just like italicizing and quoting things completely at random. My italicization and quotations don't entail anything beyond my love for randomly italicizing and quoting things...Oh and my eye rolling emoticon was selected completely at random.
Run that by me again
I posted the same question on the Adobe PS forums and got a few answers. Looks like the speed up on MacPros is around 10-15% in CS4 vs. CS3. Not fantastic, but admirable.
