Mine currently has 3GB of RAM, and I thought it was maxed out. It has
definitely been running into performance issues lately, especially with bigger
raw files in lightroom. I wonder how much difference it would make to boost
from 3 to 6GB, and how much work cost it would be.
unfortunately these older RAM modules cost more per GB as production ramps
down, it would be $50-70 to replace the 1GB with a 4GB module; generally pretty
easy to do on iMacs, though i haven't done it on your model
try macsales.com for the safe route:

or some place like Newegg if you are willing to take a bigger chance on
compatibility
(standard disclaimer; i bought my 16GB from a no-name vendor on Amazon; zero
trouble in 2 months of hot & heavy use)
