Ok, I have two machines (see my sig). I've been thinking about maxing out the RAM in both machines but I had a question. Will there be a noticeable amount of difference in the iBook (768MB vs 1.25GB)? I'm pretty sure my iMac (1 -> 2GB) will show a great amount of difference but I was just wondering about my iBook. The PC2700 RAM for the iBook is right at $90 but just wanted to know if it's worth the money.
