Well after reading most of the posts here I get some more insight in how other peeps experience the history of pc game graphics and based on that project their expectations to future developments.
I agree a catchy storyline and smooth gameplay is just as much important as super duper graphics.
I think a game is good if I'm swallowed into this virtual world and forget about the reality around me. It's like making a journey with new impressions around every corner
I strongly believe that game developers will keep on pushing the limits on what is technically possible, just to stand out of the competition and get the biggest piece of the pie. Be it with graphic realism or artistic expression, whatever sells is leading. They all want to go for the big bucks, wouldn't you? Game developers who do it out of passion to share their creative child with the world are commendable, but at the end of the day they have to pay their bills too.
Hardware developers will pretty much do the same as this is their business model, making money.
So as long as we all are paying for this and jump on the wagon the navigational lines are pretty much set, with some detours as some hypes show up along the way.
I also wonder what he impact of AI will be and how it will leave it's footprint on the future directions.
As for the obsession for graphics
And as long as there are different game pc configurations, there will always be peeps comparing to and bitching about others because that is human nature, it is in our genes. Without competition we probably would still walk aroud naked and live in caves. But we evolved (
well, some of us did 
), so there is no need for the annoyances as metioned by the OP.
So my advise; live and let live. Advise people on possible improvements based on knowledge but don't dictate, your perception might be the weird one here. Always try to look at a dilemma from both perspectives and deal with the fact that other people don't share your opinion and try to respect that.
For me personally, my rig suits me. Whatever I throw at it, it can deal with it in a way that is satisfactory for me. If not I try to tweak or adjust my criteria.
Some folks here with a waaay bigger budget (
or other priorities) have a top tier power house of a pc may find that strange, but hey, that's your problem
