Greetings and Happy New Year! Its a new year and I'm ready to pull the trigger on a new machine however I keep going back and forth on which machine. I will be mainly using the machine for Lightroom + Photoshop CC for editing and retouching. I am looking at either an i7 iMac or MBP with the discrete graphics card. I'm wondering if the new iMac will significantly outshine the new MBP or will the performance differences between the two be small? So I'm in a quandary on which way to go. I really don't need to be mobile but it would be nice once in a while. Every couple years I take a 2 week roadtrip in which I bring a laptop to back up my images. So if I went with the iMac I may need to figure out on how I would backup my images on the field. I already have a 27" external monitor so If I went with the MBP its not like I would be editing on a 15" monitor. I usually upgrade every 3 years or so if that helps. Any advice or input would be greatly appreciated!
