I’m quite satisfied with performance of my current workstation. [44-thread Broadwell] paired with 64Gb of RAM, fast NVME and [24Gb EVGA 3090Ti] shape solid desktop tool.

In 2021 i already tried out modern platform based [around x570 in conjunction with Ryzen 5950X] . System worked without any problems, thanks to modern [CanonKong Windows 7 drivers] .
Well known Chinese driver modder [Canonkong] confirmed that [64-cores/128-threads Threadripper 3995WX] based upon sWRX8 chipset works flawlessly in Windows 7 environment. Considering the news it looks like that more recent [5995WX] will also work without any issues. So, we have plenty of headroom in terms of system performance. As for me, i have no need to switch to “recent operating systems” like Windows 10/11. Here is brief [confirmation] from the WinRaid forum:
