I have seen Mac g4 800's and 1gig PC's running side by side. I don't care how much power you got in that thing, the sheer amount of crap in Windows will slow the sucker down to a crawl, the fact that there is an avarage 3 click to 1 click ratio between operations in windows and MacOS actually adds up.

Second of all, to compare to the dual 1gig mac's you are going to need a pretty hevly triked out PC, because tho you might be able to swing a faster PC it's clock speed is going to have to be 1.3 times faster than the Mac.

Third of all, WTF do you NEED dual 1600Mhz for?????? I mean does any normal application in the universe need that kind of power!!!!!!

It reminds me of those stupid kids who buy all these expensive hotrod parts for a 1983 Honda civic. It may be fast and powerful, but it ain't no Porch. Same thing with the Mac in my opinion.

Finaly, running Photoshop, and other graphics apps well, is not a small thing. The entire publishing industry is founded on this.

Mac's are damn good machines and well worth every penny. Speed is just a number and not an acurate messure of performance. I see kids bragging all the time how Quake 3 pulls 3billion FPS on their new AMD blah blah blah.. what's the point if the human eye is only capable of processing 60FPS?

Anyway, all I am saying is that Mac people are not missinformed their just realistic. Generaly with everything added in to the Mac experiance the machines are WAY faster than comparable PC's.
