Good afternoon, I am from Venezuela, a country where light is practically free and I want to start mining ethereum. I want to know what components I need to start mining. What is the best video card that does not suffer from overheating problems and also what is the best motherboard. I would like an experienced person to tell me how it has gone in this branch and if it is worth investing in components to put together our own GPU? Thank you, I expect a prompt response. Thank you very much.
