That’s seriously completely unnecessary. Video rendering and photo rendering are two entirely different beasts when it comes to performance. He does not need a 5960X, or even a 5820K, and actually could probably get by with a 6100 if he wanted to.
Anyway, any old motherboard that fits your CPU will do. As for the CPU itself, I would recommend getting a Core i3 as the performance provided by two cores with hyperthreading is perfect for day-to-day multitasking and Photoshop rendering. For a GPU, I think a 750 Ti would be your best bet – it provides GPU-based acceleration that’s sufficient for even the largest of photos your dad would be handling. The 4K monitor will be by far your most expensive part, just so you know that going in.
Thank you for the answer.
I think GauntletV2 either missed something in my post or assumed I was going to do video rendering too.
As for the monitor, yes it will easily be the most expensive part especially because it has to be an IPS panel and not the cheaper TN panels. I even tried to convince him to stick with a 1920x1080 monitor for now because 4K is going to be a lot cheaper by the end of the year.
