iMac Pro is basically a left-behind tech to Apple. It's either too old or nearly too old for new macOS updates unless you use the OCLP hack. If it's not already "vintaged," it will be very soon.
However, since it's Intel based, you could run bootcamp on it and thus at least Windows 10 and then have access to ALL Windows games... not just any one game.
On the other hand, you could take that same M4 Mac Mini budget and buy yourself a 2025 PC from a company like Minisforum and it would be all new tech inside instead of tech 5+ years old if not older. Or take a bit more than that budget and get a NUC from someone like them with a Nvidia gaming chip to boot.
Example
If gaming is your driver, while modern Macs have plenty of horses, the big games won't just come on lip service alone. If you want big gaming in 2025, go PC or PS5 or Xbox, etc. Apple verbalizes they are serious about gaming about every 6 or 7 years but money (towards it) would actually make it happen. Those other players put the money towards it and thus are much greener pastures for AAA game developers.
Another idea if you go this way, get yourself a high-quality monitor
with more than one input and you can then plug both your Mac and a PC into the
same monitor, flipping back & forth between them as desired. Some monitors have built-in KVM/hubs so that a keyboard, mouse, good speakers, cameras, etc can also be shared between whichever computer is in charge at the time.
For "basic tasks" use your existing Mini (or PC can do basic tasks just fine too).
