SO i read it that 3gb cards are more likely to phase out in 2018 due to DAG.Any suggestions?
3GB cards are not good enough to start mine any coins. Everyone usally prefers the Radeon series cards and Nvidia cards when they start the bitcoin or any altcoin mining. In these model 8 GB cards are preferable to mine ethereum and bitcoin. If you want to go with the lower end miner which can give low hash rate and clock speed. You profit will be estimated as very cheap profit.
Check the radeon 470 to start mine or go with the ASIC miner machines.
That is not correct. I have a bunch of 3 GB 1060s doing all sorts of alts via Zpool.
If you only want to mine ETH then, yes, you don't want 3 GB cards.
I am liking 3 GB 1060s right now... it doesn't take long to earn back the cost of the GPU since they are $189-$199 and they will be an easy re-sell at ~50-60% of price paid even after a year or so of use.
