I've NEVER accepted the "macs are better for graphics work" line. ; I think it would have been more accurate to say that macs were preferred by graphics professionals. ; The difference is perception (or fashion) over capability.
At the current time I, as a PC user (I'm no MS fanboy, they angered me with Vista and now I'm hyper skeptical about Windows 7, but still I do like my PC), have to at least point out that there is no 64 bit version of the latest adobe products for Macs. ; That means that even if you load up with 8 gigs of memory you won't necessarily be able to use all of it for graphics applications. ; If you start getting into very large files you won't get the benefit of greater memory usage that 64 bit mode would give you. ; You'll still have multitasking, multiple programs could each use a share of the larger capacity, but one application won't be able to use it all if you should need it.
I'm not suggesting this is due to inherent system superiority, I fully admit that Macs have made a much more graceful transition to 64 bit support. ; But I have to guess that for some reason this is harder for Adobe to manage on a Mac than a PC, otherwise they wouldn't withhold such a capability from what was supposed to be the core graphics professional system. ; I think this has been this way at least from CS3, so the limitation has been with us for two generations now.
If you're planning to keep the system for such a long time then perhaps eventually Adobe may start offering such functionality.. but at the moment it isn't there.
