I actually do make full use of the hardware decently often for data crunching/analysis, and I've messed w/ CUDA a bit before as well. Ultimately, my steam account has probably had more money spent on it than this box...but not by much. ;)
Because the effect achieved is a function of game+hardware. For a total budget of X dollars to achieve the best possible result, the hardware is a much larger component of the budget. Would people spending thousands on hardware also be willing to spend more and wait longer in order to get higher-quality video in games? Is that what the PC version is "supposed" to be about, compared to the standardised console product?
Audio climbed this curve and has topped out. Video games haven't really explored it.
(evidently it's uninteresting enough that someone's downvoted it ..)
I didn't downvote, but the whole point of the PC as a game platform is to get the best possible experience. That usually comes with a higher price tag that many are willing to pay.
Very high-end systems are more niche obviously and the price onvolved their shouldn't be indicative of anything other than enthusiasm by hobbysists. Enthusiasts in any field or hobby are usually willing to spend lots of money to get a 'superior' experience.
As for waiting for higher quality I think yes, many would be willing to wait. GTA V came out nearly two years after the console releases and I was one of those who waited for it.
It's not like I was aching with anticipation for it, I had more than enough games in my backlog to play and when it did eventually release it was much better than the console versions.
It's not like GTA V is indicative of multiplatform releases though. Most will release on PC at the exact same time and not suffer the kind of issues we have seen with Arkham Knight.
Arkham Knight's absymal PC release was due only to a shitty port by a small third party studio that was obviously incapable or unequipped to handle it. I don't think I'd even really blame Iron Galaxy for this either, I blame Warner Bros and possibly even Rocksteady for thinking outsourcing the port was a good idea.
