I have always been a fan of Macs, but have never been able to purchase one as a semi-serious online gamer who is afraid a game that I would like to play will not be compatible with Macs. I have recently found out that I can run both an Apple OS and Windows at the same time using Parallels. I currently possess a computer I built myself, a budget SFF machine with an AMD Athlon64, nVidia 6600GT, 1GB RAM, 200GB HD, and I would like to keep it, as I do not have the money to spend on a whole new computer. Can I purchase a Mac OS and install it on my current hardware? Can anyone with Parallels give me any anecdotes about playing games on Windows?
