I'm getting a new computer, and looking at the pricing on newegg, buypower, and cyberpower it looks like there's some gaming computers that are in my price range of 700-900. I just have no idea what to look for in them. I.e. CPUs, GPUs, chipsets, I'm pretty much clueless. I've looked over the "Post Your Setup" thread, but I don't want to get an overkill computer and waste $200, or one that looked good, but can't run anything. Any recommendations?
Also: It NEEDS a warranty option, my parents will buy nothing without a warranty.
