Yup, I get the feeling though entirely. Mine is still the 8700K set up that you sold me iirc. I was also tempted by your last set up you had for sale, but talked myself out of that too (did that sell btw? )Personally, I am so tempted to get the 5950x and a Dark Hero, but I already have a 10900k and maximus XII Hero, so I feel that it would be a pretty dumb move for me. Plus I would need to also get a GPU and that's a fools errand these days.
The thing is the upgrades are expensive enough that doing it just for the fun of it is a hard sell. Sub-$1000 makes it a good just for fun project by my measure. Beyond that makes me feel like I need to justify it for more "real" reasons; need more performance, need a feature that comes with the new specs, etc. I can't really get there with this upgrade.
Even my daughter is still doing just fine with the 4790K that went to her when I went to the 8700K. So I can't even justify it through that route!
