I finally just ordered my 24" iMac. I got it refurbished from the Apple Store for $1399. 2.4 GHz with 1GB of RAM (I ordered 4 GB - should arrive in time) 320GB HDD and 2600 Pro I can't wait! It shipped yesterday and Fedex says it'll be here on Sat. July 5th. I was going to order the 2.8GHz system, I think I'm starting to regret it. Am I going to see a big difference in performance with the 2.4 GHz rather than the 2.8? I won't be doing any encoding really, I'm more focused on things like startup time and the daily tasks (web browsing, email, iPhoto, iTunes.) The only game I'll really be playing is WoW and The Sims 2. I'll also be installing Vista with bootcamp. So what do you think the performance would be like at 2.4 GHz with 4 GB of RAM?
