According to an article at Popular Science, Macs are better at retro gaming than PCs. If you’re an emulation fan you should get a Mac, immediately, the article by Justin Pot says.
From the article: OpenEmu is an emulation program, and it’s by far the easiest way to organize and play a retro game or ROM collection. Also, OpenEmu is only available for Mac. This application solves just about every frustration a novice would have with emulation software, and allows users to just drag their ROM collections, connect a supported controller, and start playing.
There are other tools out there you could install that will do the job, like RetroArch for Windows or Linux. But you could probably get a PhD in computer science in roughly the same amount of time it takes to set that application up. OpenEmu is the ultimate app for computer retro gaming, and the race is not particularly close.
