i5 vs i7 iMac 5k for Graphic Design/Photography?

[np1000]

Finally decided on all my specs for a 5k iMac other than the CPU. Just needed help deciding on whether I should bite the bullet and jump to the 4.0GHz i7 or stick with the stock i5? I'm a photographer and graphic designer and usually pump through around 650 photos a week in Lightroom, of which about 50% of them are also manipulated in Photoshop.

Current specs:
-CPU – Undecided
-R9 M395 2GB
-16GB RAM
-256GB Flash Storage

Any help in regards to if I'll actually take advantage of the i7s features when working, or if should just stick with the i5, would be great! I am looking to future proof it slightly (at least 5 years would be preferable)

I no expert but I've been reading about the same question i5 vs i7. I would now myself choose the i7 for future proofing your machine. Here is a article you might like to read.
Hope this helps.
