Help me choose hardware configuration

Question

I am preparing to buy a new desktop computer.

I would like to use it for chess analysis with both StockFish and Lc0.

My budget is slightly above 2K euros.

QUESTIONS:

This is my first time choosing configuration for Lc0, so I do not know where to focus my attention.

Regarding StockFish, it should be simple? Just buff CPU + RAM and you are good to go?

Can you advise me, so I do not make a mistake during purchase (what are the things I should strive for, what to pay attention the most...)?

MY EFFORT TO SOLVE THE PROBLEM:

After Googling a little, I believe that below configuration could suit me:

• CPU = AMD-AM4 Ryzen 9 3950X (16 cores, 3.5 GHz)

• MOBO = AMD-AM4 Asus TUF B450M-PLUS

• RAM = KINGSTON DDR4 32GB 2666MHz HX426C16FB3/32 HyperX Fury Black MEM01669

• GPU = Asus nVidia GeForce RTX 2070 ROG-STRIX-RTX2070-O8G-Gaming 8GB GDDR6

• Hard Drive = SSD 480GB Kingston A400 SA400S37/480G

• Computer Case = MS WINSTON gaming ATX

• Power Supply = LC Power 650W LC6650 V2.3 + Bronze

• OS = Windows 10 Home x64

Answer 1

The biggest things that stand out here is the power supply and hard drive. For the first, getting a cheap power supply tends to be a bad idea since if it breaks, it can bring down a lot of other stuff with it. 650W is plenty, but I'd recommend going with a more established brand like corsair or silverstone. For the hard drive, given that you can get a 1TB SSD for about $150, I would do so since it will mean you have plenty of room for a 6 man tablebase (syzygy).

Other than that, this should be a really good system for both leela and SF. If you want any help with optimal settings for lc0 performance, feel free to drop by the lc0 discord!
