I am considering purchasing a 2.8 iMac and maxing out the RAM. However I'm not familiar enough with Bootcamp or Parallels to know if it is worth paying for Parallels. I would like to use Office, but not for Mac as MSDN doesn't have Office for Mac available for download. I figure Parallels would be best since it can "boot" Windows while I'm in MacOS. But what is there a performance hit? Also, if I were to game, which would be a better option? Also, can Bootcamp support other installs like Ubuntu or RedHat? Thanks in advance for any advice.
