Intel i7 4790K is the MINIMUM for DOS!
Hah, but in all seriousness, anything from 8088-Pentium I should be good... as mentioned use cache trickery to slow things down if needed.

i believe dos compatibility ends where you loose the last real isa port;
So that would pretty much include any post-486 machine ? 😉

Well, there are a few schools of thought on this...

🤣 why? i had a 500mhz machine with a working isa slot

Yeah, but it wasn't "real" as in native. 😁
If it was 100% real, it would have been connected to the front side bus of a 286 processor.
Or at least directly to the chipset in case of later processor generations (386/486).
Pentiums usually push ISA through the whole PCI conglomerate.
Anyway, never mind! 😀 I was just nitpicking here..
In pratice, ISA on an older Pentium works as good most of the time
(for example, on-boardl stuff still runs via Super I/O instead of LPC bus, etc).
In fact, I once ran an old 8bit tape controller card on a Pentium 166 to rescue data
off of my father's old QIC tapes.

It seems to depend entirely on the era and what you want to run. There's a long, long list of games with speed sensitive issues but then you have software rendered games with high resolutions for which I'm beginning to think there is no such such thing as 'too fast' - my S939 system doesn't even do 30FPS @ 1600x1200 in PCPBench and it has one of the fastest single core chips made. ISA is mentioned but there seem to be a number of PCI cards that work just fine for later DOS/SB emulation -- if you're not going to be using it for FM music for instance. So I'd say once your motherboard no longer has PCI.
