  Out her in the Maine woods without web access at the moment, so I found 
something else to do.

I did some fairly extensive editing of a 5DII file using PSCS4 on my netbook+:

Celeron SU2300, 1.8GHz dual core processor.
2GB total RAM, dynamically shared with video.
Win7 64 bit
250 GB, 5400 rpm HD about half full.
4GB, class six SDHC card as Windows ReadyBoost.
PS Performance set:
   1072 of the available 1511 MB of RAM reserved for PS
   20 history states, 4 cache levels
   Open GL Drawing off

This is considerably less horsepower than has been discussed in this thread. 
Yet editing was pretty responsive. The 
initial 16 bit file is 120 MB. Up to 3-4 layers, with masks, ~ 500 MB, and many 
history states, most operations are very 
quick. Up above that, calculation intensive things like LCE start getting slow, 
maybe 4-10 seconds, although many ops 
remain fast.

Saving a five layer PSD file was painfully slow, maybe 1.5-2 minutes ( My 
attention wandered.) The need for both reading 
the cache and writing the file on a slow rotation disk really kills write 
performance. If I did this regularly, I'd max 
out the memory at 4 GB and save to an external card or disk.

I don't know anything about Macs, other than that they are faster, smarter, 
more artistic and better looking. It does 
seem to me that super levels of all sorts of powers and capacities aren't 
really necessary for pretty high levels of 
editing.
