Comment It's not only the hardware, but also the software (Score 1) 1283
I for myself am a big fan of OS X (and all the great apps that come with it - FOR FREE! Windows doesn't even have a descent terminal), so this is one of the key reasons to buy a mac - since it wont run on PC-hardware (no matter what u pay and how it performs).
But I know a lot of people that will stick to MS Windows. Either because they use an app thats not available on Mac or just because they are used to it
Whatever the reasons: I think the new G5's are competitive machines. I am upgrading from my g3 powerbook and so even the low-end models will be a significant performance. And I am glad that I have waited and not upgraded my PC-based system that is only rarly used for quake 2, although its newer than the powerbook.
Just my 2cent!
