What he's trying to say is that is not an efficient card for ETH mining. If you want to accumulate ETH, it would be more profitable to mine another coin that your card is more efficient with and then convert it to ETH by selling the mined coins and buying ETH.

I would also suggest downloading the NiceHash miner and running the benchmark. That will give your cards hash rate for different algorithms and then use a profitability calculator to find out which are the best coins to mine.
