Re: All Sapphire 7950s (11196-19-20G) are not suitable for mining?
Yeah sparks i don't put in doubt.
One day, I saw very good the little sparks in one of my dead gpus.
When i said this issue to Sapphire forum, a mod insinuated me that i must have a quality hardware above all the psu.
And I said her that the gpu showed me sparks because i had a bad hardware such as a mobo of 200 and a Platinum PSU (Fractal Design Newton R3 1000w)
and that if I had a Diamond PSU with 110% eficiency 
i'm sure that i wouldn't see any spark. Sapphire, Sapphire...

Yup, I'm sure many have had problems with their sapphire 7950's of the most recent batch. Something tells me they were created in haste to sell to miners without doing proper quality assurance. The problem is most people don't/won't see this thread but the issue is really bad. Hopefully sapphire issues us new better cards instead of the crappy problematic cards we currently have.
