Newbie question for MacPro folks

I think I will get a MacPro, but since Adobe will not let me change CS3 window version for CS3 Mac version I will be required to run the window version on the Mac.
Can anyone tell me if Photoshop will run faster, the same or slower on the Mac than my present system on the PC.
This is my biggest concern.
Thanks,
Al

from what i hear so far, it should supposedly run faster

I would think it'd run better using OS X. CS2 would run better on a PC than an Intel Mac but CS3 should be running 64 bit with Leopard. When using Windows, it's probably running at 32 bit.
But, I haven't seen any articles or run any tests myself.

Adobe does offer a cross-grade. The only cost is shipping. Call their customer service number.
