I've ordered a new iMac recently, but I have a few programs I have for Windows that I want to keep using. Nothing intensive, just things like Guildwars, The Sims 2, and Zoo Tycoon. So far, I'm partial to bootcamp because I'm wary of the virtual machine and how it will work. However, I've got 4GB of RAM and I don't think parallels being slow is an issue. I just want to know how these games would work best on my mac. Parallels or Bootcamp?
