should I add memory?

Hardware Overview:

Machine Name: PowerBook G4 12"
Machine Model: PowerBook6,2
CPU Type: PowerPC G4 (1.1)
Number Of CPUs: 1

How much of an advantage would adding max memory? Right now, I can't get
some games to work as it's too slow. What else could I do? Any idea about costs?
Thanks,

G4, I'd add a new computer.

but yes, if you find the right RAM give it 2Gig and it'll love you. If you have to spend more than $50 then you're wasting your money.

Thanks, Kaveman. I have another computer. I use the mac for travel and
guests. You have been helpful!

I have one of these myself and they are great, its sad to see it just sitting, but time passes.
