Yep, 7950 can do something like 110-120 H/s I guess
Actually the 7950/280x is by far the best card for zcash. They cost $80 and can do 180 h/s easily constantly.
This is without mods. 110=120hash was like version 5 man. Need download version 7 for 180hash
Yep, it's true: 175-180 h/s. And no mods, only overclocking (1180/1500 for me).
BUT, there is a downfall:
ETH mining, v 7.3 - 845W from the wall on 4x280x
ZEC mining, v 7.0 - 915W!!!
