9.0 is junk compared to old ones,huge instability using asm or without
this is not true at all, i get about 2-2.50$ more a day with 9 vs 8.1
yes it fluctuates some.. but not enough to be a problem. the boost in dcr is well worth it.
For me, both are totally same. I don't see any difference at all in mining speed or other stuff.
