I am not using my old rig with RX cards because they are useless same as those old dual XEONS .
dual Opteron 6378 produces around 5kh on 350w not a bad result compared to all other CPUs which makes about 0.50$ per day and this was 1 day ago when NET HASH was 370mh.
Now NET HASH is 970Mh and by all calculators that means 0=0 .
So currently just vps mining and owners of cpus who produce 10kh earn something like 50 to 80 cents with price at lest 300EU without calculating the MB, RAM etc.
Profitability crashed even more now, 5200 h/s was $1 net then, $0.92, $0.60, $0.54, $0.48, now $0.40 if you pay $0.10 kwh.

Update: Profitability is now $0.33
