So..... The R5 2600 was installed Sunday (yesterday) morning. So far, only 1 error today, at 7:30AM this morning (usbperf). It was the first and only error since 7:55PM last night. Aside from that, only DCOM errors. The only unusual behavior I've experienced has come from the Chrome browser, but admittedly, I haven't tested Vivaldi to see if it continues to have the same issues. I have been using the Chromium based Edge browser instead, and it's been uneventful....just how I like things with my browser.
