[MacDV] Will 2gb of RAM vs 1gb make much of a difference on G4?

[Timothy Luoma]

I have a 1.5GHz G4 Powerbook with 1gb of RAM.

I'm spending a lot of time with EyeTV, Toast, iMovie, iDVD, and  
iPhoto, and have been thinking about upgrading to 2Gb of RAM.  This  
would be a big move as it would mean I'd have 2x512MB of RAM that  
would be sitting around (and would probably need to keep at least the  
one original 512 from Apple, as AppleCare wants to remove all 3rd  
party RAM if there is ANY sort of a problem).

I was talking about this with a friend who wondered if it would  
really make a difference.  He figured that the real bottleneck was  
the CPU.

I figured this was the best group to ask... assuming any of you have  
any non-dual-G5 experience (which just isn't in the budget).

Anyone have any benchmarks or experience with this?
