Currently I have one T-bird 800, and an old compaq thats running at 300 (PII). my next system mabye a PIV because of some minor t-bird compatibility problem, and core temp is too high. One more thing, I notice lately everyone is go against intel, and supporting amd , but the things I don't want either one of them to dominate the market. The fierce competition is the reason why the cpu market is advancing with speed.
