You can bump it up to 3 gig of ram - plenty really

Question 2

No you don't really notice anything - unless things have starting to go wrong. You may want to sample MainMenu as well - does the same things as Onyx but easier - both are good through.

^^
so i just need to find a 2g stick then right?

How to identify your iMac.

it looks like it yes

I don''t know why you cannot install 2 x 2gid, but all the specs say 3 gig is the max

But this article makes it clear, one slot can have 1 gig, the other 2 gig
