I ordered the following spec iMac on launch day. 27" 3.4GHz i7 GeForce 680MX 8GB RAM 3TB HDD I was struggling to justify the extra £200 for the Fusion upgrade. Am I going to regret it? I am going to buy more RAM and fit is myself. On my current machine I use Bootcamp for gaming under Windows. I know that Bootcamp doesn't work with the 3TB drive at the moment and I ordered in the hope that would change. Do I take the risk with Bootcamp and my current spec or should I (a) order the 1TB Fusion or (b) go all in and get the 3TB fusion. I don't need 3TB of storage but I think I need more that 1TB. Games are getting bigger and my Steam folder on the windows partition is getting huge! Also, would adding an external thunderbolt SSD be an option for fusion style performance?
