Graphic Card for Bitcoin Mining?

[squatz1]

No graphics card is going to work to mine any amount of bitcoin which is going to be profitable, as the market has been takenover by ASIC miners from companies such as bitmain. If you want to mine with your GPU, you're going to have to mine an altcoin which is still going to be profitable (and I would stick with that, as ASIC miners are still a pretty shaky area unless you have dirt cheap power)

So yeah, gpus can only be used on altcoins now bud.

For bitcoin mining PC needs best graphic card.Which graphic card can be used for bitcoin mining?

A GPU is not suitable for bitcoin mining on PC, as it is better to have a good processor like intel i7, intel i9 etc. But it is best to buy a special device - miner, specially designed just for this, and is much more efficient and cheaper comparing with a good CPU.
With the help of a video card you can mine Ethereum. The best price ratio for AMD RX470 video card and newer. More powerful variations don't meet the money spendings.
Take into account, that mining video card lifetime is only 6-12 month

I am planning to mine Ethereum through GPU, thinking of 1070ti variant of 8 GB. Electricity price here is moderate and may reach ROI in 8-10 months hopefully.

Dont forget, that ETH soon will change its protocol and your GPU will turn into a great gaming PC
