Which MAINBOARD and which GPU do I choose for graphics / editing (Photoshop, Lr, etc ...) ??

Hi guys,

I'm going from PC gaming to PC graphics / editing (except for modeling 2d, 3d) so I do not need a "super PC" and also I want to save some money so I have to change some components (do not worry about selling the pieces).

CURRENTLY THE PC HAS THE FOLLOWING PIECES:

- WINDOWS 10 64BIT

- MSI H270 Gaming Pro Carbon Motherboard, ATX format

- Intel Box Core Processor i7-6700, Silver

- Kingston HyperX Fury Memory Kit 16 GB, 2x8 GB, 2133 MHz, DDR4, Non-ECC CL14 DIMM

- Gigabyte 1060 OC 6 GB GDDR5 GPU

- Samsung MZ-75E250B / EU SSD 850 EVO, 250 GB, 2.5 ", SATA III

- WD WD10EZRZ Blue 1 TB Desktop Hard Disk, 5400 RPM, SATA 6 GB / s, 64 MB Cache, 3.5 "

- EVGA SuperNOVA 650 G2, 80+ GOLD 650W

(Up to here I spent € 1257.57)

THE GPUS I AM EVALUATING ARE:

- Gigabyte GT 1030 Low Profile 2G

THE MAINBOARDS I AM EVALUATING ARE:

- Gigabyte GA-H270-HD3 LGA1151 ATX motherboard

I PLEASE ACCEPT YOUR OPINIONS AND PROPOSALS FOR OTHER MAINBOARDS / GPUs OUTSIDE THOSE I LISTED TO MAKE MY CASE.
