First me, I prefer PC because i don't have MAC. They said that MAC have problem in gaming. MAC is best in editing picture and video. But I'm not in that line. I prefer heavy gaming that's why PC is for me. Yeah
Mac, way lighter, more user friendly. A big win. We got a mac pc and it's great for designing which a friend of me does over here. He draws the most beautiful things on it. Try that on a Windows pc. I know that a Windows is more common for gaming but don't forget that more and more games are also for Mac.
i would definitely go for pc as the games available for mac is so expensive and its not worth it. Moreover, there are many games which mac can't support. Furthermore, you can do alot of stuff with windows and the games are much cheaper for windows. Therefore, i would have to go with PC
of course pc is better for gaming. Have you ever seen a mac with a nvidia or ati graphics card? i haven't cause i think they aren't suited for macs so this totally pulls down the gaming experience
