Hardware Unboxed revisited the Ryzen 1700 and it still look pretty good. One thing they noticed is that some of the games are now taking advantage of the additional threads compared to the old i7-7700K and result in higher 1% low performance.
It's the typical "price against what's retailer or eBay are selling for" situation. A quick look on PC Parts Maker, the 1800X is $200 USD on Amazon. For $80USD more you get a 3700X. For $200 CAD you can get a Ryzen R5-2600 but people are selling i7-7700K for $325 on FB. Like Steve @ GN said, it's only worth $50 USD. I still can't believe people try to sell an Intel i7 8086 for $500. "IT'S A COLLECTABLE!!!!1!!!". Yeah no one cares, it's not a Ferrari F40, Porsche GT3 RS, or Kurt Cobain's guitar. It's a piece of mass produced silicon that does work or most likely access website with naked people on it.I wanted to get a 1800x last year for $140 used (august 2019). now prices have doubled lol
