Ask the photographer to recommend the computer configuration for retouching.

For photographers to retouch? A discrete graphics card is not required. Just buy a motherboard with a good monitor. Sometimes retouching will open several softwares, so the CPU can't be bad. Otherwise, sometimes it's crazy to respond when the retouching is almost finished. Personal suggestion I7 6700K. The main frequency of i7-6700K is 4.0, and the main frequency of i7-6700 is 3.4. Without overclocking, the difference is 0.6, let alone overclocking. According to the evaluation, the i7-6700k can be overclocked to 5g. I wonder if it's credible. By the way, don't forget to add more memory chips. Otherwise, the CPU is good but the memory is not enough, and the software process is easy to crash.
