Even though you are doing things OTHER than actually gaming, I expect you might do some of that as well, plus it might be necessary as a feature for what you do, but it would also be relevant to know whether or not this needs to be a Gsync display as well. I'm not sure it's a factor at all, and it does generally add expense to the cost of the monitor, but I figured I'd ask anyhow.
Talked to a few people, seems like IPS is the way to go. In general, I can probably throw 500 - 800$ at it for my main one. Not sure of that price point will land me a Gsync display, but it doesn't seem like having it would hurt. Seems like it would help smooth out the stuttering in the viewport.
One friend was saying that with the power supply in that build, I wouldn't be able to get a second graphics card. Not sure if the case can also handle two either. He's probably considering that a GPU renderer like Octane would become a tool in the future. But whether its not worth getting more power, I'll talk more with him but my thoughts were I'd like for this to be a build I could upgrade in the future. And if that's the case, he would spend a bit more for some better parts (didn't specify what)
