here are some real world tests between a boxx system and a G5 (go to page 2):
They’re about the same in terms of performance. Also pretty girls will want to lick your face if you have a G5 under your desk. They’ll also do anything to get under the desk just to be near it.
I heard that it’s going to be a rip-off copy of Mac OS X but will be a better attempt than XP as they’re taking much more time, so I suppose if it tries to imitate the best OS there is then that’s a good thing.
Lukep (the person who builds/maintains the Mac Blender binary) explained that there is a problem with all versions of Blender and any machine that has over 2GB Ram. This causes problems with large renders.
Conclusion, get either one. Mac is more stable, secure, sexier, easier to use/setup, is better for multimedia, has better build quality, no viruses (so no virus software), has less trouble-shooting issues and has a better developer environment with it being a unix system so it’s easy to compile open-source unix software.
But you won’t get as good gaming since things like half-life 2 isn’t on Mac. Despite the fact Doom 3 and Halo is, you will likely be missing out on some great games. Some software too as 3ds max is Windows only. Also, repairs are cheaper on the PC (but usually happen more often).
If you’re a hardcore gamer, the PC is unquestionable. Otherwise I recommend the Mac.
Either way, there will likely be times when you question if you’ve made the right choice.
