why the 6600 is used instead of the 6800 as the base GPU?
Even Dell's new XPS line starts with a 6800 Ultra with an upgrade to the 7800. The 6600 is still only a middle-of-the-road gpu.
>>Because Apple has a tradition and *reputation* to uphold
why I don't see anything about SLI if the PM can use two gfx cards?
The technology may be a bit premature, but still.
>>Indeed. The new PM does not support SLI, which is a bummer. Again, Apple seems determined to consistently...year after year... cripple their graphics performance...though to be fair, this update is probably the least guilty of this *tradition*. What is @#%&#@# insulting is a Rad 9700 in a $2500 Powerbook without 1920 x 1200 res. That's should be illegal! I can say that because I own one
why the PCI-express slots are 2-4x, 1-8x, and only 1-16x?
Wouldn't it have been better to have
two 16x slots? Perhaps gfx cards don't require 16x--does anyone know?
>>yep. It would have made MUCH more sense to have 2 -16x slots. No PCI X support...zip, nada, zero...that's premature in my opinion.
how a user will benefit from the dual chip, dual core PM?
>>Someone using After Effects(2d) or Maya(3d), for example, will be VERY happy. Can you say.... "render times" ...multitasking while rendering, etc. Watching paint dry on the wall during a render gets old...trust me. If you don't use these types of apps..or you play a lot of games...don't waste your $$$....and it IS a waste of $$$. That's my two cents.
Won't this require a better compiler to effectively utilize all four cores? Obviously, I am not a PM user, but I am curious if this top-of-the-line PM will really yield performance that is worth the price, especially with the Intel transition coming. Hey, if Apple is already dismantling their hardware teams to focus on the coming Intel shift, it only makes sense to me that they are also shifting their software resources. Sure they will support PPC through Leopard, but where will the real optimization be seen? I'm betting Intel. I'm also betting there will be no OS support beyond Leopard.
