Yet now that we finally have progress in the form of more cores per CPU, people are whining and moaning about 12c/24t for $499, that will sit on a motherboard (with socket) that you could have owned for 2 years already, and may last another generation, and then how ever long after before it is retired.
2016 - Mainstream Desktop - 4c
2017 - Mainstream desktop - 8c
2019 - Mainstream desktop - 16c
Bigger gap in the last two, but it proves the point that people are complaining about progress, because they personally have no use for it. I remember when I got my 200MMX, cost a small fortune, but man it was a huge upgrade from my Pentium 120.
I had a new pentium 90, then had it swapped for the floating point bug for which Intel held aroudn £460 on my credit card until the return was received back.
When I was about to upgrade I was gutted to find doubling the RAM made a huge improvement to performance in Doom, I'd have done it much sooner if I'd known.
Back then A CD reader and sound card was ~£250.
The most frustrating part of the current situation is the pointless refusal to list prices of the motherboards. I can view specs and even download manuals and drivers on the Gigabyte site (assume samples are out) but there is no official pricing. Poor show AMD.
For the 3700X and 3800X most B450 and X470 boards range from fine to very good and will be the entry level platform for now.
In the product stack, it's easy to forget that the 3800X is claimed by AMD to be a 9900K class processor and that performance is available on two generations of motherboards and the 3600X is not far behind for gaming.
Until these go on sale, 9900K is about the best performing gaming CPU you can buy so that's a pretty high bar for mid range.
X570 seems to be priced close to HEDT entry level with cheapest 4 layer boards at ~ £200, 6 layer boards with a few extra features are £250+ and then sky's the limit.
They do seem a little on the expensive side compared to Intel, however the X470 boards which seem capable of 12-16 cores with some boost are £200 to £250 anyhow though these typically have a few extra features.
Personaly looking at the Aurous Pro (no Wifi) with a 3900X but the board needs to be priced around £250 or I'm going to feel abused given the Intel equivalent is £160.
CPU/Motherboard costs are far more tolerble these days as there are a range of decent performing options and even older platforms are still holding up well, though 4 cores are finally becoming to be a bit of a bottleneck in some titles.
The biggest cost in PC's these days seems to be graphics with the ever increasing tier pricing and relatively short life, through I don't think it helps we've all been pushing the resolutions.
Back in the day, Doom was usually played ~ 320x240 with a big border on a 14" or less CRT as PC's couldn't handle full screen games.
Definitely lot more bang for you buck these days.
