I have a SP 1.8Ghz G5 with 1.25GB of RAM right now. I was thinking about going with 2 more 512MB sticks to bump it up to 2.25GB total because they are so cheap ($45 per stick of Crucial RAM). Will I notice any improvement? I know going from 256MB to 1.25GB was a noticeable difference. I do some editing in Final Cut, some light Photoshop work, etc.
