Definitely this. I was blown away going from 1080p to 1440p. I thought 4K was cool how I could see the textures a clearer but went back to 1440p for the more convenient scaling and performance. It will be interesting to see what happens beyond 4K because it seems completely pointless.

For desktops I completely agree. I look forward to being proven wrong though. 

I just don’t believe 8K is going to be that great for PC gaming. You reach diminishing returns with pixel density sitting as close as the average PC user does to their screen. 

Now, 8K TVs? That I understand.
