i remember my k6-2 did very well in sisdoft sandra benchmarks though, i was reasonably happy with the speed it was just the instability
I remember K62 for the heat dissipated and the instability yeah. I solved this increasing to 2,3v (2.2v original got blue crash screens) the vcore.
But for sure the K62 was not a champion of performance.. I remember that when I bought a the 550Mhz version the difference was really so little. Nothing compared with the Duron 750... this rocked!
