The real max is indeed 3 GB.

According to the performance benchmarks from Other World Computing  
[1], XBench performance is best at paired 2 GB, Halo is best at  
paired 2 GB, and all Photoshop tests are best at paired 4 GB with  
unpaired (1 GB + 2 GB) 3 GB a very, very close second.  (Paired is  
better performance than unpaired for this chipset, all else being  
equal).

We could go with 3 GB for $179, or with 2 GB from Apple for $135  
(which turns out to be a pretty competitive price for 2 x 1 GB).  I'm  
inclined to think that XBench is a better measure of compilation  
speed -- the most intensive task the system will be performing --  
than Photoshop filters. Seem reasonable?
