T-Rex miner is awesome
, some times you really need to give different miners a try to see how they performs, I used to praise phoenix miner but something just pushed me to give T-Rex and trial because some are saying it's better and I wasn't disappointed, from 31MH to 31.868MHs, that's almost an extra 1 MHs, T-Rex miner rocks
T-Rex is the best nvidia miner for 3000 series our there currently. The others haven't updated yet to best build the dag.
There is a test from 2miners that shows nbminer slightly ahead for the 1660 cards.
