So I'm contemplating the purchase of a Mac Mini. However one of the things I would like to be able to do with it is play my classic... between five to twenty year old... PC games. Windows 7 has a lot of compatibility issues with these old titles, so I figured I would run an old copy of XP. I know BootCamp no longer supports XP, but I'm wondering if I can still get good enough performance out of a Virtual Machine?
