Actually, you can ignore the bickering. Very easily. If people really are sad enough to get so worked up over the merits of AMD vs Intel, then they really need to get a life outside this place. If that's what floats their boat, fine. As long as it doesn't violate the ToS, then they can continue. There's nothing in there to stop them.
If you're looking for information on what to buy, consult the stickies at the top of the boards. Most have very helpful information. Or maybe read the articles on Toms Hardware.
If people having a pop at each other over the merits of AM2 vs LGA775 or whatever offends, your sensibilities, then I'm sorry. I'm not going to stop people having a debate over, esentially, their strong feelings on their preferred product. If someone tells someone to "fuck off you twat" in the CPU forum, then yes, I will. If someone posts porn, or seriously threatens another member, then yes, I will deal with it. That is what is universally decreed as the issues that can and do arise on here. Everyone knows they are wrong and everyone knows that the perpetrator should be dealt with, and they always, always are.
