I am completely illiterate when it comes to PC software. Over the next few months, I would like to get Bootcamp running with Windows XP. I am planning on playing Star Wars: The Old Republic when it comes out, and since it is looking likely that it won't come out for Mac's, I need to look into Bootcamp and Windows. What I have issues with, is that I see so many different options for Windows XP when I search for it. And considering it isn't $15, I have to make sure I'm buying the correct software. I'm pretty sure that what I need is "Microsoft Windows XP Professional - Full Edition with Service Pack 2" correct? What is the price I should be paying, and can anyone recommend the best site or provide a link that can verify exactly what I need (such as an Amazon page or whatever). Thanks for any help, as I am just clueless when it comes to this Windows stuff, and I have to make sure I get it right. Also I have a May 2009 17" Macbook Pro w/ 2.93 GHz and 4GB RAM, if that matters any.
