GPU mining is still profitable in 2019, though with the advent of ASICs (Application Specific Integrated Circuits), it has become more difficult to turn a profit with GPU mining. That said, if you have a GTX 970, you can still mine Ethereum and other cryptocurrencies, though you may not be able to turn a profit.

The GTX 970 is a high end GPU that was released in 2014. It is based on the Maxwell architecture and has 1664 CUDA cores.

The GPU has 4GB of GDDR5 memory and a core clock speed of 1165MHz. The GTX 970 is a good choice for mining as it has good performance and is relatively power efficient.

When mining Ethereum, you will need to use a mining software such as Claymore’s Dual Ethereum miner. This software will allow you to mine Ethereum as well as another cryptocurrency such as Decred or Siacoin.

You will need to set up a wallet for the other cryptocurrency as well.

The GTX 970 is still a good choice for mining in 2019, though you may not be able to turn a profit due to the difficulty of mining and the competition from ASICs. If you are willing to mine without turning a profit, then the GTX 970 is still a good option.
