Hey guys, I have a 24" iMac that I bought about 3.5 years ago. The specs are as follows: 2.66 Ghz Intel Core 2 Duo 4 GB 1067 MHz DDR3 NVIDIA GeForce 9400 256 MB I installed Lion on it. Would it be worth it to upgrade the RAM to 8 GB? since it currently has 2 X 2 GB modules in it, I would have to basically throw those out and purchase 2 new 4 GB modules. I'm wondering if it's even worth it to spend the money, or should I just save the money for a new computer sometime in the near future? I just don't want to throw money away on something that will be old and outdated soon.
