Hi, I'm new to this
Can I mine either Litecoin or Etherium using an amd or nvidia graphics card that one might have in a standard home gaming computer? How much hash power do I need. The card probably has about 25 MHash/s to 35 MHash/s
I know that's not a lot but would I be able to make even like a dollar a day with that?
What about graphics cards that are more advanced with 300 or more MHash/s but where I still only use one and not a whole rig?
There are cards that have a large advantage over their counterparts for certain algorithms currently. Specifically, for Monero you can run a Vega 56/64 with cast xmr and get 2050 h/s with a single card where a 1070 gets 500 h/s. However, for Ethash you'd be hard pressed to get more than 45 MH/s out of any single card.
As for litecoin. I would not recommend mining that with a GPU. It has ASICs readily available
