No there is a forum called Computer chess, or talkchess. there is a thread titled "buying a new computer" Good luck!!
Thanks, yes, I have seen and read all pages of that thread too. Didn't it go off topic with discussions on various other things than computer build?
Anyway, here is my opinion and plan, in case someone with the same questions is interested:
As mentioned, the Ryzen 3000-series seems interesting and gives good performance for the price. Most reviewers online consider the R5 3600 a sweet spot. I also don't think it is worth paying $150 extra for a 3700X to get some more nps for Stockfish, although it might be a bit more future-proof with 8c/16t instead of 6c/12t and can give a bit more performance for SF10.
As mentioned before, for me it is better to spend the money on a Gigabyte Aorus Elite X570-board instead. That spares me the trouble of flashing BIOS, gives PCI4.0e support and also USB3.1 gen 2. Btw, this mobo lacks debug LEDs, but I hope I can live w/o them, will let you know if that was an incorrect assumption! Further, chances are a bit higher that this mobo (instead of the B450/x470-series) lets me upgrade the CPU in a few years and it has decent capability for me to try OC if that is not possible (I won't start with OC-ing, just basically run stock).
I'll pair the CPU and mobo with Corsair Vengance 3200 MHz 2x16 GB RAM, CMK32GX4M2B3200C16. It doesn't seem worth spending more money on higher frequency. I'll try OC and change timings and voltage instead if needed.
For Lc0, I hope to buy another RTX 2060, but from what I have read (that is where above mentioned thread gives some hints), it might not be the best price/performance upgrade, though. Scaling is less for the newer nets, and not like for a/b search engines. To have room for another GPU, I need a PSU of at least 850 W it seems like. That is more expensive than my first plan of a decent 750W PSU I found on sale, but so be it. Skimping on the PSU seems unwise, but 1000W seems to be PSU-underload.
The case will be a Fractal Design R5 to accommodate all the parts and have good airflow.
Those are the things I have decide to include in my build. I will add a Samsung 970 EVO plus and than another M.2 NVMe SSD.
