Hi there, Dave. I've been away from the hardware scene for a while and trying to keep up with the latest tech. I'm considering a Ryzen 7 2700X (second generation) CPU for my next build. For future compatibility, I'm thinking about an x570 chipset motherboard, especially the Asus TUF gaming X570-plus with Wi-Fi. The specs are listed here: https://www.asus.com/au/Motherboards/TUF...fications/. It says under storage that M.2 Gen 4 SSDs should work with Gen 3 CPUs, but not Gen 2 ones. Does this make sense? Or could a Gen 2 CPU still run an NVME SSD at a slower speed? I found a discussion on the AMD community site (https://community.amd.com/thread/241486) and think I'm interpreting it right—using a Gen 4 SSD with a Gen 2 CPU might not be worth it. Any help confirming my understanding would be great. Cheers!

The M.2 connectors function as PCI-E 4.0 exclusively when paired with a Ryzen 3rd generation processor. With a second-generation CPU, the connector operates in PCI-E 3.0 mode. Your SSD will automatically adjust and operate at PCI-E 3.0 speed, which is slower—up to 4 GB/s instead of the full 8 GB/s—but it will still function properly. You might also consider the Gigabyte x570 Aorus Elite, priced similarly but offering a USB 3.1 Gen2 port supporting up to 10 Gbps for the front panel. The only drawback is its single video output, which restricts you to one monitor if you intend to use integrated graphics.

Thanks for the feedback. I only need a few USB 3 ports—it won’t be used for gaming or anything else besides processing astro images with PixInsight. The system will run Kubuntu Linux, which offers about a 10% boost in performance compared to Windows, OS X, or freeBSD. USB 3.1 isn’t essential; USB 3 will work fine for my needs. I might consider the Gigabyte recommendation later, but based on what you said, I could upgrade to a more powerful motherboard and CPU in the future, especially since cores really impact performance during benchmarking.
