So I'll be using my new 5k mostly for photo editing in LR and Photoshop. Some 4k video stuff here and there. I opted for 16gb ram and SSD, but was torn on whether to choose the 395x 4GB graphics upgrade or the i7. I ended up going with the bigger graphics card, thinking the i5 3.3 would be plenty fast. Wondering if I should have done the other way around? I couldn't stomach getting both. The machine was already extremely expensive! In addition to video editing here and there, I just couldn't help but assume the bigger graphics card would help push all those pixels around. I'd hate to see laggy UI anywhere. Any thoughts? I'd rather not delay my order, but if the i7 will make the bigger difference over graphics, I probably should.
