Hi, I was wondering which would be best for me. I'm currently getting the parts I need for my computer, and I was thinkin' about getting xp home or professional and then I began to look into it, and there are so many versions I don't know what's I should get or not. I thought xp would be my best bet because I've heard so many problems with Vista, but I may be wrong and vista may be the better choice. But with either there is like a 32 bit and a 64 bit, and a sp2 and 3 pack, and it's all just so confusing. This is my first computer that I'm building so all of this is pretty new to me, I'm just so used to having a computer with windows already on it, I would like to get XP professional or Vista Ultimate, but I don't know which, or 32 bit or 64 bit. So thanks in advance for any help, and here is my setup: clicky
