I'd still call myself an amateur in regards to image editing. The recent departure of Aperture has allowed me a chance to make the decision to up my game a bit in post processing. I'm not sure everyone would agree with the results but I've been pleased so far. Point of the post? Just info for others who might be making similar decisions. My old editing setup was Aperture, NIK plugins, and my 2012 Macbook Pro (laptop screen). I have "upgraded" to Capture 1 Pro, NIK plugins, a ASUS Pro 248Q (pre-calibrated monitor), and a Spider 4 Express calibrator (and the 2012 MBP). I'd call this a budget upgrade into a setup that can be calibrated. The monitor is working out very well so far and man is it an upgrade from my laptop screen. A lot more detail and the accurate colors really help. Here's two versions of an image. The first was from my original setup and the second is from the new "calibrated" setup. My personal opinion only, of course, but I think temperature, color, and brightness are better on my new setup.
