i ask about graphic card nvidia gtx 750 ti 4go
how many i get by day in $
which the best altcoins to mine it
It's a viable Monero miner, should pull about 250 hash/sec
Not sure if it's worth trying to mine anything else offhand.
It's not worth mining Monero either. 250 H/s come to a profit of $0.02 a day with a 120w power consumption assuming $0.12 electricity.
OP needs to better these numbers in order to make anything that is worth even considering. Assuming a lower, $0.08 cost per KWh, OP would be making $0.14 daily.
Might as well go outside and pick up pennies off the streets.
