First AMD system I built was with the Athlon XP 2800+ cpu, right after that was the big upgrade to the Athlon XP 3200+, I still have it in a box, stored away. I have bought earlier AMD cpu's, but they were in store bought prebuilt systems, so I didn't count them as my 1st AMD cpu. Have several various different generations all the way up to Zen 4 now.
