With Nehalem so close, I would forget earlier chips and motherboards.

Memory bandwidth 2008 Penryn Mac Pro made a huge improvement over
Clovertown and Woodcrest

Xeon requires FBDIMM memory and it will be interesting to see how well
DDR3 and built-in memory controller improves things.
Photoshop CS3 + Harpertown on Mac Pro 2008 (early Leopard OS X 10.5)

Older Apple Mac Pro 2007's 4-core vs 8-core, Photoshop performance

I have seen people complain about low memory bandwidth and thrashing,
but never seen any indication there even is any relation to number of
cores to amount of memory, or ratio of one to the other, maybe its an
issue with systems other than Mac OS X 10.4 or .5.
If your files get to 1GB and larger, then definitely more RAM.
Of course CS4 is now 64-bit app (will take a major rewrite so Mac won't
get 64-bit version until it is ported to Cocoa and Snow Leopard). And it
seems CS4 isn't all its cracked up to be...
.... opening and saving a file with Photoshop CS4 remain a
single-threaded task. ... when enabling Open GL drawing in CS4, supposed
to speed rendering, it was actually slowing it down!
