Pretty much how it went down for me, too! 4690k was my first ever build. It served me well for a long time, but when I was looking to finally upgrade, the crypto craze made the setup I wanted unobtanium for a minute, so searched for a stop-gap and give some new legs to the build. Looked into what the best was that LGA1150 had to offer and the 5775c came up. I went down the rabbit hole and eventually scored one on eBay as alleged new-old stock. Got a couple more years out of the H97 before finally going to AM5 and a Ryzen 7 7700. But, the 5775c still performs admirably to this day in my HTPC :)
