There is a lot of misinformation here. Windows 8 and SimCity work fine. I have used it throughout each beta and now when I can actually get into a server it plays just as it would on any Windows 7 box. In fact, every game I've played before on Windows 7 works on 8. There seem to be no compatibility issues that I have come across yet. If you are running into issues on 8, its most likely something with your computer, its hardware, or a driver issue.
