my 7950's do 270 sol with this software, seems about right i guess?
cant believe i got hold of 2 7950's for 150 bucks in these times, not counting on any huge profits ofcourse, just some hobby mining.
You might be able to get 300 sol if you do a little overclock with core and memory.
Try 1100/1575 or something like that and see if its stable.
Yes you got really lucky.
I remember you could buy the 7950 BRAND NEW for like $199 back in end of 2013.
