if you are asking which software then claymore for AMD and ccminer for nvidia if u mean what coin then mybe try  whatomine and it will tell you ur best options

560 is no good for mining how every 580's are expensive but if u get 8gb one u can duel mine and ROI will be fast

i would suggest u not to go for hashcash .. dont take risks

90% load is high .. keep it below 70% i think

Scam??
