New Gaming PC inquiry

[Kubaton]

Soo.. Im looking to gain another gaming pc, but I thought to ask here first if there's anything I should be warned about.

A very long time ago Im pretty sure I read that this emulator will only run if you have windows 7 OS...

Does it run on anything newer, with mass ram and multi cores etc? Any issues I might run into that are avoidable?

Thanks

PS, this old antiquated pc is going to be my wifes gaming pc when I get her playing.. LOL!
