I'm going to be getting a new iMac soon, probably the new one when it comes out. I want to save as much $$$ as possible, and I want 2GB RAM. I was wondering, which method would be cheaper: 1. Order it with 2GB RAM pre-installed 2. Order it with the standard ram option and buy two 1GB sticks. Replace the factory-installed RAM and sell the old RAM on eBay. I'm not sure if replacing the RAM would save me much money and be worth the trouble. What do you think?
