No PC satisfies this condition. A PC that was high-end in 1995 is not low end in 2020, it's a toaster / doorstop. Progress has slowed but not to that extent, and new tech, hardware capabilities, etc are introduced that soon make it to even "low end" PCs. The game would be either comparable to current games (which isn't terribly exciting), or very unpleasant to play on current PCs.
Just flip the question. What game could you send back now that would be playable in on a 1995 computer? Would someone from 1995 benefit from it in any way? The biggest benefit I could see would be an indie game that you could extract 25 years of gameplay evolution from.
(you can and maybe should simply bypass this issue by sending a whole portable system with the game).
What if its a very good indie game using an older game engine
