Probably will stay with P3 800 & up but will consider AMD Thunderbird.I am willing to spend $ to get decent quality and reliability.Probably will also need a new power supply, right? Comments please? Also want a good soundboard so I can use my computer for telephone calls. Any suggestions? Also would like to know best video card
