Greetings from Germany! I will buy an iMac next month and I'm not sure what configuration makes sense. First of all: I will use the iMac for professional photo and some video editing. And ordinary things like surfing and text editing. I present you two different variants, which are quite similar in price. I would like to have your opinion. Version 1: 21.5 "- 1 TB SATA - 16GB RAM - 3.1 GHz Quad-Core Intel Core i7 instead of i5 2.9 GHz - NVIDIA GeForce GT 650M with 512 MB Price: 1,737 Version 2: 27 "- 1TB SATA - 16GB RAM - 2.90 GHz Quad-Core Intel i5 - NVIDIA GeForce GTX 660M with 512MB Price: 1,719 The 21.5 "with the i7 have a more powerful CPU as the i5 27", but I can not estimate if the "faster effect" would be recognizable. And which display would generally be better? A display with 21.5 "or one with 27"? i would be glad about helpfully answers!
