Its really hard to get hold of cheap cards now. If you going to start i recomend to have some pc skillz, its going to be really hot. Buy good quality power supply so you dont blow out.
My best tip is to use the mine as a longtime investment and mine coins with low difficulty you belive in.
Specific hardwhare, you have to go on forums and take a long read.
Im the type of person that researches A LOT before making any decisions...Im also very bullish long term on the industry so I wouldn't expect quick money.
I wouldn't really say pc skills lol, but I have a good knowledge. I would probably look at better quality cards, long term investment.
Getting hold of any amd card is hard right now. Ita a mining bubble^^
I know!! I saw this coming so I invested in INVIDIA as a company about 2 years ago. At that time I started reading into mining but thought that would be the better investment.... I just think it is time to try to get into the mining game. At least as a expensive hobby lol $$
