I would... to some degree. The issue with 4k is that the display folks are waaaay ahead of the content producers here. Film and media should be reluctant to adopt 4K for several reasons:
* Many folks have not yet migrated from DVDs to Blu-Rays
* Maintaining production lines for DVD, Blu-Ray, and 4K probably would not be offset by customers willing to spend even more above the Blu-Ray pricing for a 4K disc.
* The mainstay product sold by media is a combo package - DVD + Blu-Ray + Digital. Adding a 4th offering to these combos is very difficult.
* Monopolistic ISPs have little incentive to upgrade bandwidth to support 4K streaming, despite Netflix's apparent willingness to provide that content.
Most of the above fortunately does not apply to video games. There is no need to package or sell the "4K" version of a game. (Or is there? OH GOD THE HORROR. Please don't tell EA about that idea.)
However, the late 2010's saw the conjunction of budget 4K displays and the cryptocurrency boom. Although graphics card prices are just starting to normalize, the crypto boom seems to have forced graphics card pricing to be 1-2 years behind the display market.
Yes, I do. I have a CRT for Smash Bros: Melee, a 144hz monitor for FPSs (at 1080p), and then my comically big 4k TV at 60hz for stuff like Witcher or other casual AAA titles. The TV is coming over Steam Link anyway, performance is dropped in favor of sheer visual beauty.
Sure maybe I don't need it, but I can afford it and it brings me delight...
