Thanks guys! I ended up going with the cheaper RX480 8GB since there was a sale on that specific model. As for monitor i purchase an LG 27UD68-P since it has freesync in case I ever do game, I liked how thin the bezel "looks", the specs looked decent enough and now that I have it installed with an Amazon Basics Monitor arm it looks sexy (and allows super simple adjustments). I know you guys said the extra resolution isn't needed in LR... but I LOVE the extra screen real estate that it feels like I have... sad thing is that this resolution has made me realize I may need to upgrade to Win 10

Win 7 overall the elements scale poorly.
So far the processing has definitely sped up (moving around sliders, seeing live adjustents etc) and exporting is not choking the machine as bad as it was before the upgrades were tossed in. So was it probably overkill? Yea... but then again it should mean that I won't have a NEED to upgrade much for a while :P
Personally I think Win 10 even has OSX beat on the screen scaling front, no matter what size monitor you are using. My friend has the previous 2560×1440 iMac and has to run it in a lower than standard resolution to that he can read it, due to eyesight issues, even with his glasses on. Actually he has issues with a 15" 1280 pixel wide laptop screen, which he runs at lower than native. To my eyes the screens look really bad thanks to trying to scale them in that way. With Win 10 all you need do is set the scaling to 125% or 150% on a normal display, or any of the greater than 200% options on my 5120×2880 monitor. All of the screen elements get bigger, including images in a browser, which on an HTML page scale too, although just bring up a JPEG file and you get the scaling go back to "native", so you can see everything really well, but you are still seeing the monitor at native resolution, so things like font smoothing work very well indeed. It's so good that I can set a screen size he can read, and still look at all of the larger elements without seeing artifacts, so we both win. He spent about 3× as a minimum buying the iMac for what he wants to do, and then runs it with the monitor looking that bad that he might as well have spent £300 on a complete computer system, including a cheap large screen 1920×1080 screen.
