I’m looking at purchasing an iMac. Looking at 2 different 2011 models. The first one is the 2.7ghz i5 12gb RAM with 512mb graphics card. The second is the 3.1ghz i5 16gb RAM with the 1gb graphics card. I’m not a massive gamer but looking at installing an SSD at some point. Is there a massive difference between the two? The first one is £380 and the second is £460, are these reasonable prices? Any info is greatly appreciated.
