I haven't seen any tests, yet I've seen Sempron/Socket-A in action and it was impressive. I also have Athlon 64 and Athlon XP pc's at home and I don't think K8 is so superior. In non-sse2 non-very-memory-intensive applications it performs better, but not "turbo-charged". Besides, AMD is pricing Socket-A Semprons even higher than s754 versions. Considering the fact that s754 is clocked lower than sA of the same PR, it can be hard to determine the speed difference. Anyway, I really think there's nothing for us to argue about :) Gareth is staying with s754 and we should be glad for him :) Very best wishes, Andrew P.
