I am looking at buying a 27" iMac. I appreciate there are new iMacs coming out at some point, but when that will be, who knows. Plus, my 2011 iMac is slow and I end waiting for the beachball to stop spinning. Anyway, I was about to purchase the 27" with the Radeon M395, 2TB fusion etc, but I then noticed the M380 model and I was wondering what the difference is between the two graphics cards. No matter what I go with, it has got to have the 2gb fusion drive. I am a photographer and use my current iMac for Lightroom and Photoshop, email and internet. I do not use it for design, gaming, video etc. Any help would be appreciated.
