All I did for that one was search “Threadripper” and look at the pictures for ones with 4x x16 slots that were not hella expensive. There are technically filters for that, but, I don’t trust people to list their things correctly.
For which chipsets, ect to look for, check out this page. If you click on Learn More next to AM5 for example, it tells you how many PCIe lanes are on each chipset type which can give you some initial search criteria to look for. (That is what made me point out x670E as it has the most lanes, but is not newest gen, so you can find used versions.)
Make a textfile you sync between your devices. Save the URL, book name, or whatever; each on a new line.
You can tag them at will. Put “#TagName” next to an entry and later you can ctrl-f “#TagName” (or anything else) in the file. Notepad++, grep, and other tools will even give you a list of everything that matched your search criteria if you want to see all items that match at once.
I like to keep things simple!
