iMac 2.8GHz Intel Core 2 Duo 2GB+ MBox2+Reason 4?HelpPlease

[YellowMonkey]

I'm not very familiar with PC's and even less with Mac's as I've never had one. All I know is my PC's chipset is incompatible with Protools which I learned the hard way

I'm looking at buying a new compture and I want to make sure it will work for Protools great, will it? I went to 2 different Apple stores and they weren't able to tell me anything, maybe because they want to sell Logic.

So iMac plus Reason 4.0 + Mbox (how do you know which mbox to buy)?

Basically the 3rd package with maybe upgrading the ram: Is it worth upgrading to 4GB memory? What is the difference?
