12 years ago I built a PC that worked for… 12 years. The mainboard died recently so I have to build a new one. So, I started to document myself.
CPU
I am interested in single-core high-frequency CPU because I will use the PC mostly to compile Delphi code. I have found some charts that compare the CPU value (speed divided by price) and AMD Ryzen 7 7800X seems the best.
Here is the CPU selection guide.
Motherboard
CPU selection was relatively easy. The mainboard is a different story. For the mainboard I compiled a color-coded list of boards based on the new x870 chipset. The table is an extension of this one.

You can also find the list above, updated, here.
x870 vs x670
Now I am wondering if it really worth paying double for the new x870 chip-set since it is bringing very little (almost zero) value.
- x870 brings USB 4.0 and WiFi7 (though these might be available also on x670 main boards.
- B650 still offer the best value while being fully capable of supporting the new Ryzen 9000 CPUs.
- If USB 4.0 is needed and you have an old board, it may be more cost-effective to buy a USB 4.0 add-in card.
- The new X870 supports higher memory frequencies (with Ryzen 9000 in mind), but the increase in freq is only minor.
- The chipset has nothing to do with controls for audio, networking, and additional PCI-e or USB ports, speaker headers, seven-segment displays, and dual-BIOS or BIOS flashback support. So, x870 has no words to say in this!
I think we can summarize that x870 is not worth its money. Not at this price.
