I have been using PII,PIII,K2,K2-3D,K3, and now i can not wait for the K7 because of the fact that intel needs some good compatetion. For some one that thinks that the PII is more stable than the K6-2 3D then he must be a intel person. The K2 350 is almost as fast as the PII 400. It also is much easier to load software. YOU must be using crapy motherboards. Buy K7's if you want the best performance for your buck.
