I'm building a new system with an Athlon Slot A Motherboard. In the board specs it states that the processor support is for a slot a athlon only. I went on E-Bay and bought a 700 AMD Thunderbird Slot A. From what I understand, as long as its slot a, its an athlon. Am I going to have a compatability problem? Is this processor considered an athlon slot a processor or an Athlon-Thunderbird slot A? I'm still waiting for the mobo and CPU. I thought that slot a are all athlons. I hope I didn't get the wrong CPU. Can someone give me some input?
