So I own a Mac laptop that runs games fairly well. I'm thinking of purchasing Sins of a Solar Empire, and Parallels, which will let me run Windows XP (I already have a copy of XP just lying around). So I was wondering: Does anyone else do this? Or have they heard of anyone doing this? Does this work, or would Sins run extra-slow so that the gameplay would be compromised? Thanks for your feedback
