Hi all, i am about to purchase myself a new computer rig that I will be building myself. First off, I have never installed any operating system. As well as built a computer, which I what I am doing. But I do have a question. While looking at newegg.com to buy XP, I noticed there is one version with a Service Pack 1 and another one with Service Pack 2. What is the difference, and which would you reccommend to someone who will be doing mostly gaming, but eventually programming and media things. Thanks for any help in advance.
