I swear by AMD !!! I want nothing to do with anything else. My computer was built as well and when I first had it done it surpassed any computer you could buy and for half the price. My husband and a friend built it in less than a day. It is still great. We need more ram now and a new processor just to make it faster and bring it right up there with the computers you can buy today. But I don't think I will ever buy a factory made computer.
