I just finished my first gaming build thanks to this place. I've Ben playing on it a few days now and no problems. I trying to determine if I need AntiVirus now though. This computer is for online gaming only. I've heard some people say avg is good for gaming computer and some say that if only used for gaming and no surfing then I don't need one at all. Can anyone please tell me what to do here. If I do need one I don't want one that will slow my computer down .
